Why Cut Is so Much Important In diamonds
The cut grading currently only applies to Round diamonds as they are technically easier to measure in terms of light performance. Other shapes – such as Princess cuts, Cushions cuts, Emerald shapes, do not have a cut grading on their certificate but OCS Diamonds provide an estimated cut grading based on equivalent parameters.
Cut grades range from Excellent, Very Good, Good, Fair and Poor. The grading takes into account various attributes of the diamond that cannot be seen or measured with the untrained eye. An excellent cut grading will have the best light performance, mainly influenced by the relationship of surface table and the depth of the diamond (not too deep or too shallow).
Diamond Cut
The cut of the diamond not only refers to the shape of the diamond but it is also a factor in determining the ability of the diamond to reflect back the light falling on it. The brilliance and awe of a diamond depend largely on its cut. Hence, a poorly cut diamond can look lifeless and dark regardless of its colour and clarity.
An “ideal” diamond can not only have better brilliance compared to a poorly-cut diamond, it even looks larger (diameter) than a deeply-cut diamond of the same carat size
Ideal cut diamonds
A diamond that is cut into ideal proportions and angles, either round, brilliant or princess cut, with excellent symmetry ratings and polish, is known as an Ideal cut diamond. An ideal cut diamond will be perfectly proportioned to refract light in the correct angles to produce the fire and brilliance that makes the viewer go mesmerized. Sunny diamonds offers a nice collection of ideal cut diamonds perfect for all occasions.
Hearts and Arrows Diamond
If you’re a diamond enthusiast, you might have probably heard about the super ideal-cut Hearts and Arrows diamond. The Hearts and arrows diamonds are precision cut diamonds showing an arrow and heart pattern while viewed from a special tool, indicating the diamond has a perfect optical symmetry. Because of its exact angles and symmetry, the diamond presents the viewer with 8 hearts with tiny ‘v’ shapes while viewed from its pavilion side.
The Hearts and Arrows diamond collection at Sunny Diamonds are masterpieces; a perfect expression of love and a perfect diamond.
Understanding Brilliance, Dispersion & Scintillation
A high-quality diamond will produce a diamond with dazzling brilliance, fire and scintillation. When a beam of light falls on a diamond, the light will either enter the stone or reflect off. The light that gets reflected off the surface is known as a diamond’s brilliance. The light that passes through a diamond, where some of the light rays get separated into flashes of colour. The process is known as dispersion. This division of white light into its spectral colours (or the result of dispersion) is known as fire. The spectrum of colours viewed by the viewer as he/she moves the stone back and forth is known as scintillation.
The Effects Of Light On A Diamond
The science behind a diamond’s brilliance depends on its great ability to bend, slow and direct light as it passes through. The cut of a diamond determines how well the diamond is able to re-direct the light back through the surface of the diamond. Light travelling at about 186,000 miles per second, when passing through a diamond is reduced to about 77,000 miles per second, close to the maximum for any other transparent substance (another reason why we are OCS Diamonds).
Expert Tip
It is very hard to see the difference between an Excellent and a Very Good cut diamond as the direction of light is the same in both cut gradings. We therefore recommend you try to stick with an Excellent or Very Good cut, but if needed to fit the budget, a Good cut can offer an excellent-value alternative without any major compromises. Just make sure you are not on the “Deep” side or you will end up with a diamond that looks smaller than the actual carat weight.
For white or colourless diamonds (as opposed to coloured diamonds, which is a whole different story), the diamond industry has adopted an alphabetical colour scale from D to Z, with D as the highest grading. As you go down the scale, the diamond starts to develop a yellow or brown tint.
Experts in the world of diamonds determine the colour by comparing a diamond against a master set of diamonds of different colours. Without comparing diamonds side by side, it is very difficult to see the difference between a D and a G.
Completely colourless diamonds (such as D and E) are much rarer than others which is why they come with a higher pricing premium. The key question is always where to draw the line when choosing the colour of a diamond – how far can you compromise colour before the diamond is too tinted? The answer to this question is relative to your budget and quality expectations.
categories – colourless, near colourless, faint, very light and light. The colour that is predominant in a diamond is yellow, caused by the trace element nitrogen.
Diamond Color
While shopping for a diamond, the colour of the diamond is an important characteristic. Interestingly, it is preferred to select a diamond with the least amount of colour, since a diamond that is chemically pure and structurally perfect has no hue. The colour of the diamond is graded on a scale from D (colourless) to Z (light yellow or brown) after analysing the stone under controlled lighting and other precise conditions. The diamond colour grades are divided into five broad categories – colourless, near colourless, faint, very light and light. The colour that is predominant in a diamond is yellow, caused by the trace element nitrogen.
While comparing the colour between two diamonds choose diamonds that are at least two colour grades apart to better understand the difference in hues. It will be nearly impossible to see any colour if you are viewing the diamond in the face-up position. However, as you view the diamond from its side profile you will be able to notice some colour; even though a diamond is always appreciated from the face-up position and not the side.
Colorless Diamonds (D-F):
The stones within D-F is said to be the most valuable and rare of all the diamonds. While the diamonds between D-E range are virtually colourless, the F coloured stones will show an undetected amount of colour while viewed face down by a professional.
Near Colorless Diamonds (G-J):
The near colourless range of diamonds might appear colourless to an untrained eye especially if the diamond has been mounted. However, it displays a slight hint of colour when viewed face down against a clear white background. These range od diamonds offer an amazing value of their price.
Faint Color Diamonds (K-M):
The diamonds under the faint colour range will display a trace amount of colour when viewed from the face-up position.
The most common colour found in a diamond is yellow. That said, at times you will be able to notice a brown colour in a diamond. This is because of the internal graining. Internal graining is the result of structural irregularities mainly caused by impurities like nitrogen.
EXPERT TIP 2
H graded diamonds are often considered on the border between premium colourless and tinted diamonds, and therefore offer great value without any visible yellow or brown tint unless compared side by side with a whiter diamond.
EXPERT TIP 2
K and L are acceptable on a GIA certificate in terms of tint if that major compromise is needed to reach size within a budget. 77 Diamonds strongly recommend setting these diamonds in Yellow or Rose Gold jewellery to make the diamond appear less tinted.
EXPERT TIP 1
For colourless diamonds the differences between D to G are barely visible but can offer 20 to 40% better value. D is generally more for the investor or diamond connoisseur.
EXPERT TIP 1
I and J colours will generally face up white from the top, but you will be able to detect slight yellow or brown tints when viewed from multiple angles. 77 Diamonds highly recommend staying with GIA only for these colour grades, as any other certificate in this range is likely to fall below your colour expectations.
How to choose a clarity grade?
The diamond clarity refers to the absence of inclusions and blemishes within a diamond that can affect the overall beauty and durability of the stone. Therefore, it is important that you select a stone which is void of inclusions and blemishes. While selecting a stone, always stick with diamonds graded “VS2” or higher to make sure you are selecting a diamond clean of visible inclusions and blemishes. Purchasing an SI quality diamond can be rewarding, but it’s best to have the stone reviewed by a Sunny Diamond expert staff before completing the purchase. This will help you to choose a stone that is beautiful and doesn’t have any inclusions visible to the naked eye. Balancing the clarity grade of your diamond to its colour is another way to make sure you are getting a stone worth your money. To do this, focus on clarity grades of VS2 or higher if you are interested in the D-F colour range. If you are going for the G-I colour range, then it’s better to combine with SI clarity for excellent values.
The 4 Diamond Clarity Factors
Size
If the characteristic is very evident, it negatively affects the degree of purity.
Number
Refers to the number of easily visible features. The fewer observable characteristics there are, the higher the degree of purity.
Position
If an internal feature of the Diamond is located under the table or near the pavilion, it can affect the refraction. Therefore it can create a more evident impact on the degree of purity of the Diamond.
Nature
The Diamond crystal may have formed naturally with inclusions. The nature of a diamond feature is related to the type of inclusion and its impact on durability.
Diamond Clarity FAQ's
Why VVS Diamonds And VS Diamonds Are The Best Value
Remember that a Flawless (FL) or Internally Flawless (IF) Diamond belongs to the highest quality ever. The consequence of being extremely rare and therefore very expensive at the time of purchase. To escape from a too high evaluation, you should consider selecting a diamond with some inclusions that are not visible such as a VVS or VS purity.
Sometimes lowering the cost does not alter the beauty, luster, and brilliance of the diamond.
Diamond Clarity/Shape
Some shapes or cuts of Diamonds require a higher purity than others. For example, the emerald cut or the Asscher cut requires a higher purity precisely because you can better see the possible presence of internal characteristics through the sparse stepped facets.
For these cuts, you must choose a higher grade of diamond such as IF or VVS to ensure that the internal inclusions are not seen with the naked eye.
Diamond Clarity/Size
Fancies Diamonds are measured on a separate color scale and have a higher value than colorless diamonds.
The Diamond Clarity in the Certificate
In the certificates issued by the GIA, diagrams express the mapping of any inclusions or internal characteristics present in a Diamond. They allow understanding if the interior features can have greater or lesser visibility to the naked eye.
For example, if the inclusions are positioned outside the diamond, they will be less visible than on the center of the stone.
EXPERT TIP 1
As magnification is needed to see impurities in diamonds with a VS1 grading or higher, a choice of VS1 or higher is a subjective quality choice which goes beyond what can be seen to the unaided eye. Larger Diamonds with these higher grades are much rarer and therefore command greater pricing premiums, and also tend to perform better as an investment.
EXPERT TIP 2
Although SI1 and SI2 are in general not eye clean, the impurities may be light in colour or scattered and so in up to 20% of cases, SI1 graded diamonds may appear to be eye clean. That number falls to just 5% for SI2s.
There are many different types of impurities, but feathers and crystals are the most common forms of inclusions found in diamonds.
Carat Weight
When it comes to diamonds, the carat refers to the weight of the diamond. The word ‘carat’ is named after the ‘carob’ seeds, which served as a perfect counterweight to a diamond and was used to measure the weight of the stone prior to the twentieth century.
Diamond Size and Diamond Carat Weight
The carat weight of a diamond is proportional to its size. When a rough stone is cut and polished to form a fine diamond(s), about 2/3rd of its total weight will be lost. Since it is rare to spot a large rough diamond of high quality than smaller rough diamonds of similar quality, a large single diamond of, say, two-carat will be priced higher than two one-carat diamonds of the same quality.
The weight of a diamond will increase much faster than it increases in actual face-up diameter/width. To make it more clear, consider an ideal cut diamond of one-carat will measure approximately 6.5mm in width. Now, a diamond twice that weight will measure only 8.2mm in width – gaining only approximately 30% increase in width.
Which Carat Weight Is Right For You?
This is not an easy question to answer especially because it is a choice that depends on one’s personal preferences and budget. However, when you are viewing a diamond engagement ring, you are most likely to notice the size of the stone in its face-up position. It is difficult to measure the carat weight of stone just by looking at it. Even though the carat weight affects the price of the stone, it is always ideal to give more importance to its cut and diameter while shopping for your diamond engagement ring.
Diamond Shapes
Diamonds come in different shapes and styles of unique qualities. Therefore, it is important to have a basic knowledge about the different diamond shapes before selecting your diamond. Sunny Diamonds offers the highest quality certified diamonds to satisfy the diamond enthusiast in you.
Emerald Step Cut Diamond
Also known as the ‘Square Emerald Cut’, the Asscher cut diamonds are made using a step-cut process and have cropped corners. The presence of the cropped corners gives the Asscher cut diamonds an octagonal shape at first glance. Like Emerald cut diamonds, the Asscher cut diamonds have the clarity of glacier-water ice – bright, shiny and clear – allowing the viewer to see all the way to the bottom of the stone. However, with Asscher cut diamonds, inclusions are evident to the naked eye and hence it is important that you select a flawless or a diamond as close to flawless as possible.
Round Brilliant Cut Diamonds
Also known as the Round diamond, the Round Brilliant cut diamonds are so far the most popular shape for diamond engagement rings. The Round Brilliant cut diamonds are cone-shaped to maximize the light return through the top of the stone. The diamond is cut to have 58 facets (33 on the crown and 25 on the pavilion). You can see, the relationship between the angle of the crown (steep and above the girdle) and the pavilion (shallower and below the girdle) is complementary to each other
Cushion-Cut Diamonds
A perfect combination of the Old Mine Cut (popular during the late nineteenth and early twentieth century) and the modern Oval-Cut, the Cushion Cut diamonds are considered as an antique cut that has a classic, romantic appeal and consist of 58 facets. Since the cutting of the diamond was done by hands (instead of machines) in the ancient days, the Old Mine Cut diamond features large facets and rounded corners, designed to capture the beauty of candlelight.
Emerald-Cut Diamonds
Also known as a Step-Cut, the Emerald cut diamonds are known for its beauty and precision. It may lack the brilliance of triangular and kite-shaped facets, but it gains extra popularity in its extreme clarity. Looking into an Emerald-cut diamond is more like looking into glacier-pure ice. This particular cut got its name because originally this style of the cut was used only on emeralds.
Heart Diamonds
Considered as a classic shape for diamond engagement rings, the Marquise-shaped diamonds are boat-shaped brilliant stones. Like any other fancy-cut stones, colour and clarity are the two most important qualities of the Marquise-shaped diamond. It uses a cutting process similar to that of a Round-cut diamond. In Marquise-shaped diamond, the diamond cutter maximizes the carat weight of the stone by elongating it into its distinctive boat shape. This boat shape of the diamond helps to reduce inclusions while retaining as much of the unblemished stone as possible. However, the elongated shape can cause colour and clarity imperfections than the traditional Round-cut diamonds.
Oval Diamonds
A most modified version of one of the most popular cuts – the Round Brilliant Cut – the Oval diamonds are perfect for those who would like an unusual shape for their diamond but also want to look like the traditional Round-shaped diamond. The Oval-cut diamonds create the illusion of length and thus is perfect for those with elegant elongate fingers.
Pear Diamonds
The pear-shaped diamonds are the combination of the traditional Round-cut diamonds with a less common shape to create an unusual shaped diamond without compromising in its brilliance and can still make the light dance like in a Round-shaped diamond. The Pear-shaped diamond consists of 58 facets, allowing the light to pass through it the same way as in a traditional Round Brilliant cut. However, the shape of this diamond is subjective and its size and shape are really a matter of personal choice and taste.
Heart Diamonds
Considered as a classic shape for diamond engagement rings, the Marquise-shaped diamonds are boat-shaped brilliant stones. Like any other fancy-cut stones, colour and clarity are the two most important qualities of the Marquise-shaped diamond. It uses a cutting process similar to that of a Round-cut diamond. In Marquise-shaped diamond, the diamond cutter maximizes the carat weight of the stone by elongating it into its distinctive boat shape. This boat shape of the diamond helps to reduce inclusions while retaining as much of the unblemished stone as possible. However, the elongated shape can cause colour and clarity imperfections than the traditional Round-cut diamonds.
Princess-Cut Diamonds
Considered as a classic shape for diamond engagement rings, the Marquise-shaped diamonds are boat-shaped brilliant stones. Like any other fancy-cut stones, colour and clarity are the two most important qualities of the Marquise-shaped diamond. It uses a cutting process similar to that of a Round-cut diamond. In Marquise-shaped diamond, the diamond cutter maximizes the carat weight of the stone by elongating it into its distinctive boat shape. This boat shape of the diamond helps to reduce inclusions while retaining as much of the unblemished stone as possible. However, the elongated shape can cause colour and clarity imperfections than the traditional Round-cut diamonds.
Radiant Cut Diamonds
The Radiant-cut diamond combines two of the most prominent traditional diamond cutting styles – the Round brilliant cut and the Emerald cut – to create an untraditional yet brilliant style for your diamond dreams. Created by Henry Grossbard in 1977, the Radiant-cut diamonds were designed to create something different from what was available at that time without losing on its beauty and brilliance.
Diamond Anatomy
The four most important characteristics to understand while purchasing a diamond will be- Cut, Clarity, Colour and Carat weight – otherwise known as the 4Cs.
Table: The table refers to the largest polished facets located on the top of the diamond.
Crown: The top part of the diamond extending from the Table to the Girdle is known as the Crown. The Crown consists of Bezel facets (Crown mains), star facets, upper Girdle facets (upper halves), and a Table facet.
Girdle: The Girdle refers to the very edge (widest edge) of the diamond where the Crown and Pavilion meet.
Pavilion: Pavilion refers to the bottom part of the diamond that extends from the Girdle to the Culet.
Depth: Depth refers to the total height of the diamond which extends from the Table to the Culet.
Culet: Culet refers to the small or pointed bottom part of the diamond.
Make sure you understand the basic anatomy of a diamond before purchasing one. Learning deeper about the diamond will help you better understand and appreciate the intricacies of a diamond. It will also help you to communicate better with the experts and choose a diamond of your liking.
Proportion – Understanding Brilliance, Dispersion & Scintillation
A well-cut diamond will exhibit three main characteristics – Brilliance, Dispersion and Scintillation. When a beam of light falls on a diamond, the light will either enter the stone or reflect off. The light that gets reflected off the surface is known as a diamond’s brilliance. The light that passes through a diamond, where some of the light rays get separated into flashes of colour. The process is known as dispersion. This division of white light into its spectral colours (or the result of dispersion) is known as fire. The spectrum of colours viewed by the viewer as he/she moves the stone back and forth is known as scintillation.
Proportion – Understanding Brilliance, Dispersion & Scintillation
The symmetry of a diamond refers to the precision and the exactness of shape with which the various facets in a diamond are aligned and interset. Even though symmetry plays a much important role in low-grade diamonds, they are very important in high clarity graded diamonds.
Wavy Girdle
In an ideal cut diamond, the Girdle of a diamond should be a flat plane, parallel to the table. A wavy girdle is when the girdle “waves” as it wraps around the diamond.
Crown & Pavilion Misalignment
A well-proportioned Round Brilliant diamond, the top of the pavilion mains and the bottom points of the bezel facets should meet precisely at the Girdle. If the diamond’s crown and the pavilion is misaligned then it is labelled as asymmetry flaw.
Extra Facets
The extra facets are man-made flaws on a diamond. Typically, the extra facets are found near the girdle or pavilion.
Off-Center Culet
The symmetry of a diamond refers to the precision and the exactness of shape with which the various facets in a diamond are aligned and interset. Even though symmetry plays a much important role in low-grade diamonds, they are very important in high clarity graded diamonds.
Off-Center Table
The Table (the largest facet on a diamond) should be always placed at the centre-top of the diamond, parallel to the Girdle. An off-centred Table can cause uneven crown angles from one side to the other.
Table & Girdle Not Parallel
If the Table and Girdle are not parallel to each other, the Crown angle will be much steeper than the other.
Misshapen Face
An ideal-cut diamond displays a regular octagon-shaped Table with eight sides of equal length that run parallel to the opposing opposite facet. A misshapen face is when the facets are not properly shaped or they are not of the same size and shape as others.
Faces Not Pointing Up
Facet patterns of a diamond are meant to show a precise arrangement of perfectly shaped facets. However, some diamonds display facets that are not properly pointed.
Naturals on Crown and Pavilion
The original ‘rough’ of the diamond is meant by Natural. Naturals always start or occur out on the Girdle. They either dip towards the Crown or the Pavilion.
What Is Diamond Polish?
The polish of the stone is a very important character in determining the overall brilliance of the diamond. It determines how well light is able to pass through the diamond. The stones with poor polish will display microscopic polish lines that can blur the surface of the stone affecting the light entering and exiting the diamond. Therefore, it is always wise to pick laboratory certified diamonds to ensure good, very good or excellent polish. One of the major reasons behind poor polish is because the diamond cutters who handles the diamond try to reduce their cost by not spending enough time polishing the stone.
What Is Diamond Polish?
GD, GO, G – Good, Very difficult to see under 10X magnification
F, FR, FA – Fair, Noticeable under 10X magnification
PR, PO, P – Poor, Easy to notice under 10x magnification/Visible to the unaided eye
VP, VE – Very Poor, relatively easy to notice with the unaided eye
EX or EP – Extremely Poor, Obvious to see with the unaided eye
The difference between these grades may be little to an unaided eye. Normally, these differences will be visible only under magnification. Therefore, a diamond with a polish rating of Good can still be a very valuable stone. However, those stones with grades Fair (FR) and Poor (PR) indicate that the flaws can still be visible to an unaided eye thus affecting the beauty of the stone.
Mass production of rings with poor quality control can result in porosity or rough spots in the metal. Porosity is those little surface holes on the ring that worsens as it goes deeper in the metal. Porosity can make your ring weak thus breaking it down eventually.
What Is Diamond Polish?
Fluorescence is a natural phenomenon exhibited by certain minerals and gems by emitting visible light when exposed to ultraviolet light. For example, while held under the ultraviolet light, a diamond will display a soft colour glow, known as Fluorescence. However, not all diamonds fluoresce. Based on this the diamond Fluorescence is graded between faint to very strong.
What are the different types of Fluorescence?
The degree of Fluorescence ranges between faint to medium to strong to very strong. When the stone exhibits very faint glow while shown under the ultraviolet light is graded as Faint whereas the one that emits maximum light is graded as very strong. Even the colour that’s emitted by the diamond might vary. While the most common colour emitted by the diamond is Blue, other colours like Yellow, Green and White might also be visible.
Does Fluorescence affect the Diamond?
Being Fluoresce will not affect the quality of your diamond in any way. However, a yellow coloured diamond can appear more white in the presence of strong blue Fluorescence. At times, your diamond can appear milky or oily under such circumstances.
Ideal Cut Diamonds
A diamond that is cut into ideal proportions and angles, either round, brilliant or princess cut, with excellent symmetry ratings and polish, is known as an Ideal cut diamond. An ideal cut diamond will be perfectly proportioned to refract light in the correct angles to produce the fire and brilliance that makes the viewer go mesmerized. It is normally used as a benchmark for grading all other diamonds.
The term ‘Ideal Cut’ was first coined by a Belgian diamond cutter, Marcel Tolkowsky in the 1900s after analysing the Round Brilliant cut diamond. He took into consideration both the Brilliance and Fire of the diamond. Even though Tolkowsky’s ideal cut is not perfect, it still serves as a basic global guideline for ideal cut diamonds even though individual counties have still made their own modifications.
Today, we also take into consideration the finding of another gemstone cutter, Bruce Harding. It is he who came up with the other computer models and technological scopes for ideal cut diamonds in the 1970’s. Sunny diamonds offers a nice collection of ideal cut diamonds perfect for all occasions.

Color & Intensity
Three different criteria are used in determining a fancy colour diamond’s colour and intensity
The primary colour of the diamond; Pink
The secondary colour of the diamond: Purplish
The intensity of the diamond’s colour: Fancy, Fancy Intense or Fancy vivid.
While the tone of the diamond’s colour is determined by the primary and secondary colour of the diamond, the strength of the colour is decided by its intensity. As the colour intensity of the diamond increases the value of the diamond goes up. The fancy colour diamonds can be divided as – faint, very light, light, fancy light, fancy intense, fancy vivid/fancy deep/fancy dark.
Fancy Yellow
Also known as Canary Diamonds, the Fancy Yellow diamonds are one of the most loved fancy diamonds. You might be familiar with white diamonds with its slight yellow shade listed on the far end of the diamond colour scale; Y – Z. However, the fancy yellow diamond is far different from that.
A diamond can be categorised as fancy yellow when it is graded according to the terms: light yellow, fancy light yellow, fancy yellow, fancy intense yellow, fancy dark yellow, fancy deep yellow, and fancy vivid yellow. Normally the fancy yellow diamonds will have an intense vivid hue which marks them different from the other diamonds. This rare beauty of the fancy yellow diamond makes them expensive per carat.
What gives these fancy yellow diamonds their colour is the presence of Nitrogen. Almost 60% of the fancy coloured diamonds are yellow diamonds.
Sunny Diamonds offers a wide range of fancy yellow diamonds in many different styles and carat sizes. Fancy yellow diamonds can be the best choice if you are looking for something different than the mainstream. They will look stunning when set in platinum or white gold setting.
Fancy Pink
One of the rarest and most alluring diamonds found on the planet, the pink diamonds are some of the most prized possessions you can own. The pink diamonds are graded according to the terms: very light pink, light pink, fancy light pink, fancy pink, fancy intense pink, fancy vivid pink, and fancy deep pink.
Except for their rare beauty, the exact cause behind this hue is a mystery. Scientists think it could be because of an atomic level lattice defect resulting in the absorption of selective light thus producing the pink hue.
The very saturated pink or purplish pinks are an absolute rarity that when released into the market for purchase they often get sold for millions of dollars per carat. People usually collect fancy pink diamonds as a collectors’ item.
Argyle Pink Diamonds
Fancy Green
After fancy pink diamonds, the second rarest fancy colour diamond in the market will be the fancy green diamonds. The colour of the fancy green diamond ranges between blue-green to yellow-green (because green is a mixture of blue and yellow). Certain fancy green diamonds can also exhibit grey or brown hue. Since the fancy green diamond is incredibly rare they are also absolutely valuable. The green diamonds are graded according to the terms: faint green, very light green, light green, fancy light green, fancy green, fancy intense green, fancy dark green, fancy deep green, and fancy vivid green.
The green fancy diamonds are formed over millions of years. They get their green colour after it has been exposed to beta and gamma rays during the formation of the stone. In certain cases, the green colour of the diamond will be present only on the surface, also called “skin stones’, which might fade gradually. Therefore, pure fancy green diamonds are an extreme rarity.
Sunny Diamonds offers a wide range of fancy green diamonds in many different styles and carat sizes. Fancy green diamonds are a great option when looking to add to your diamond collection. They will look stunning when set in platinum or white gold setting.
Diamond Fluorescence
Fluorescence is a natural phenomenon exhibited by certain minerals and gems by emitting visible light when exposed to ultraviolet light. For example, while held under the ultraviolet light, a diamond will display a soft colour glow, known as Fluorescence. However, not all diamonds fluoresce. Based on this the diamond Fluorescence is graded between faint to very strong.
What are the different types of Fluorescence?
The degree of Fluorescence ranges between faint to medium to strong to very strong. When the stone exhibits very faint glow while shown under the ultraviolet light is graded as Faint whereas the one that emits maximum light is graded as very strong. Even the colour that’s emitted by the diamond might vary. While the most common colour emitted by the diamond is Blue, other colours like Yellow, Green and White might also be visible.
Does Fluorescence affect the Diamond?
Fancy Brown
A fancy orThe fancy brown diamond provides an elegant alternative to the much normal white diamond. It gets its brown hue because of a change in its molecular structure. The different grades of a fancy brown diamond include the light brown diamonds otherwise known as the Champagne diamonds and brown diamond with shades of orange, otherwise known as the Cognac diamonds.
Sunny Diamonds offers a wide range of fancy brown diamonds in many different styles and carat sizes. Fancy brown diamonds are a great option when looking to add to your diamond collection. They will look stunning when set in platinum or white gold setting.ange diamond might exhibit brown, yellow or pink shades or overtones. For a fancy orange diamond to be considered orange, it should not have any traces of brown, which makes the diamond an absolute rarity.
The orange diamonds are graded according to the terms: fancy orange, fancy intense orange, fancy vivid orange, fancy deep orange, and fancy dark orange. The fancy orange diamond is normally come from the Argyle mine in Australia and from South Africa.

Diamond Certificate
The cost of a diamond depends on these unique specifications, otherwise known as the 4C’s – Colour, Clarity, Cut and Carat. Even though carat determines the price of a diamond to a large extend, the colour, cut and clarity determines the look and feel of a diamond.
GIA Diamond Certification
A diamond or gem that comes with a GIA certificate has been analysed by an unbiased gemologist. The GIA certificate assures the buyer that the stone is certified by an institute that upholds the highest standards of science, integrity and professionalism.
AGS Diamond Certification
The AGS follows an unbiased and conservative approach towards diamond grading. This has made them one of the most respected gemological labs in the world. That is why an AGS certificate assures the buyer an accurate evaluation and analysis of a diamond.
HRD Diamond Certification
Currently, the HRD represents global diamond trade to diamond organizations and public governments. Consequently, it monitors and reports the export and import of over half of the world’s loose diamonds.
HRD also leads the industry in advanced research and education in diamonds and other gemstones. That is why an HRD diamond certificate is highly regarded among consumers and jewellers.
When you buy a certified diamond from Sunny diamonds, you know that they have been verified for their quality. Moreover, certified diamonds have a higher value than non-certified diamonds in terms of resale and upgrading. With our extensive collection of certified diamond jewellery, you can be at ease while shopping at Sunny diamonds.
Why is a Grading Certificate Not Enough?
Let’s have a look at the certificates.
(Example A) 1.01 Carat, I-Colour – Internally Flawless (IF) Excellent Cut Round Diamond
(Example B) 1.01 Carat, I-Colour – Internally Flawless (IF) Excellent Cut Round Diamond
(Example A) 1.01 Carat, I-Colour – Internally Flawless (IF) Excellent Cut Round Diamond
(Example B) 1.01 Carat, I-Colour – Internally Flawless (IF) Excellent Cut Round Diamond
That is the difference between looking at the actual diamond and choosing one based on its grade certificate.

Conflict-Free Diamonds
At Sunny Diamonds, we care where our diamonds come from. Therefore, every diamond we sell is certified conflict-free in compliance with the Kimberley Process, and the UN resolutions, which means, all the diamonds are ethically sourced and isn’t connected with any sorts of rebel groups. We follow binding contracts with our suppliers, guaranteeing that the diamonds sourced through them, which are members of the professional diamond trade, abide by all the applicable laws and are certified conflict-free.
Diamonds that don’t abide by the laws are known as blood diamond or conflict diamonds.
What Are Eye Clean Diamonds?
How each retailer define eye-clean diamonds may vary. However, there are three major points to note as you talk about eye-clean diamonds.
1.Distance and point of reference
2.The lighting under which the diamond is evaluated
3.The eye vision of the observer.
GIA and AGS define the Flawless (FL), Internally Flawless (IF), Very, Very Slightly Included (VVS1 and VVS2), and Very Slightly Included (VS2 and VS1) as eye-clean diamonds. Whereas, the Slightly Included (SI1 and SI2) diamonds may or may not be eye-clean. The Included (I1, I2 and I3) diamonds are not considered eye-clean.
Sunny Diamonds utilizes the power of Artificial
Intelligence (AI) and Deep Learning to uniquely analyze a diamond’s attributes. This revolutionary process is called Deep Grading™ and allows us to provide the most accurate assessment of whether a specific diamond is eye clean or not.
How to Choose the Perfect Diamond
Before buying a classic diamond it is important that you understand to differentiate between a perfect diamond and not-so-perfect diamond. The four most important characteristics to understand while purchasing a diamond will be- Cut, Clarity, Colour and Carat weight – otherwise known as the 4Cs.
How to Choose the Perfect Diamond
Before buying a classic diamond it is important that you understand to differentiate between a perfect diamond and not-so-perfect diamond. The four most important characteristics to understand while purchasing a diamond will be- Cut, Clarity, Colour and Carat weight – otherwise known as the 4Cs.
The 4 C's:
A diamond that is cut into ideal proportions and angles, either round, brilliant or princess cut, with excellent symmetry ratings and polish, is known as an Ideal cut diamond. The Hearts and arrows diamonds are precision cut diamonds showing an arrow and heart pattern, maximizing the diamond’s fire, brilliance and light dispersion.
Clarity – The diamond clarity refers to the purity of the diamond or the absence of inclusions and blemishes within a diamond that can affect the overall beauty and durability of the stone. According to the grades assigned to diamonds, the flawless diamond is represented by an ‘F’ while a diamond with inclusions will be described by an ‘I’. People do appreciate diamonds with inclusions, as long as they are not visible to the naked eye.
Colour – The colour of the diamond is graded on a scale from D (colourless) to Z (light yellow or brown). The diamond receives a grade after analysing the stone under controlled lighting and other precise conditions. Normally, buyers prefer a diamond with the least amount of colour, with the diamond grades J, K & L offering the best return for the money paid.
Carat – When it comes to diamonds, the carat refers to the weight of the diamond. One carat is equal to 0.20 grams. The price of the stone is proportional to the weight of the diamond, although it might also depend on the other three ‘C’s.
The shape of the diamond is another important factor while purchasing a diamond. Sunny Diamonds offers diamonds in a variety of shapes including, round, princess, cushion, emerald, marquise, square, heart, oval, pear and radiant. Finally, the most important thing to keep in mind before choosing your diamond will be to understand the anatomy and proportion of a diamond – brilliance, dispersion and scintillation.
Take into account your budget and preferences. To example, some customers like big diamonds with lesser grades, and certain others prefer small stones with higher grades. Hence, when we say a perfect diamond, it also means ‘the diamond perfect for you’.
Diamond Care
For that added shine, you can soak your wedding ring or engagement ring in window cleaner after cleaning it in a mild soap solution. Remember not to soak the ring more than a minute since window cleaners contain some hard chemicals. To make sure you rinsed all the windows cleaning liquid off your ring, wash it with the same mild soap water and later warm water before drying it.
Use a toothpick to remove the dirt that gets accumulated between the diamond and the prongs. However, be extra careful not to scratch the metal. Use tweezers to remove small pieces of cloth fibres that get stuck within the setting, again, be careful of the metal.
Ionic cleaners are used in cleaning the diamonds. However, avoid this method if your wedding ring or engagement ring is set with stones other than diamonds. The electrical current during the ionic cleaning process can have an adverse effect on certain gemstones
A diamond can only be scared by another diamond. So make sure you don’t store two diamonds together or with any other metal, as your diamond can scratch your other jewellery.
