Independent Lab Certification (IGI & SGL)

  • Third-Party Proof: Every piece is strictly audited and certified by independent global authorities (IGI or SGL).
  • Laser-Inscribed: Center gems feature a microscopic lab report serial number etched on the edge for permanent tracking.
  • Verified Alloys: Labs verify and stamp the exact metal purity hallmarking alongside the gemstone metrics.
  • The Nickel-Free Guarantee: Most allergic skin reactions to jewelry are caused by cheap nickel alloys. Our jewelry is 100% nickel-free and lead-free, guaranteeing a clean, rash-free wearing experience even in warm weather.
  • Engineered Against Tarnish: Whether you choose our solid 18K, 14K, 10K gold, or our premium Platinum 950, our precious metals are mixed to guarantee they will not oxidize, fade, or discolor over time. You can safely wear your jewelry every single day without losing its rich luster.
  • No Green Skin: Because we entirely reject base metals, copper fills, and flash-plating, our jewelry will never tarnish, oxidize, or turn your skin green or grey.
  • Micro-Prong Precision: Every accent diamond or moissanite is meticulously set under microscopic magnification. Prongs are rounded into smooth, snag-free beads that lock the stones in place without catching on fine fabrics or silk.
  • Reinforced Gallery Rails: Our ring mountings and pendant baskets feature integrated structural gallery rails. This architectural design distributes impact shock evenly, preventing center stones from shifting or loosening over a lifetime of wear.
  • Artisan Mirror Polishing: Before your piece is set, the entire metal chassis undergoes a multi-stage high-gloss hand polishing process, maximizing internal light reflections and giving the metal a liquid-like mirror shine.
  • Armored Courier Delivery: Your finished heirloom travels through an express, fully insured armored courier network. For your security, a physical adult signature is strictly required upon delivery.
  • The Luxury Presentation Vault: To maintain absolute discretion and surprise, the parcel arrives in an unbranded outer box. Inside, it opens into a heavy timber, velvet-lined presentation vault designed to protect and showcase your piece for years to come.
  • Lifetime Warranty Support: Every finished jewelry creation is backed by our signature structural integrity guarantee, covering manufacturing verification and offering direct access to our master workshop for future sizing or maintenance needs.
  • Our Lab Grown Diamonds are EF colour VVS-VS clarity & All 0.75 ct+ are IGI certified and available in options of colour, clarity, Cut & Size
  • All products Can Be Ordered in available 3 Metal Tone options: Yellow, White, and Rose 
  • Ladies ring pricing is maximum for ring size US8 and for Gents, it is till ring size US9.
    Additional charges will be applicable above that.
  • Each piece is customized and made to order. Diamonds can be set according to your preference

The Stone(s)

The focal point of this solitaire ring is a single, hand-selected 1.00 carat heart-shaped lab grown diamond. Displaying a color grade of EF and an eye-clean clarity profile of VS+, the gem exhibits symmetric brilliant faceting with balanced lobes and a crisply defined central cleft. These precise geometric proportions control light dispersion to ensure optimum fire and brightness.

Because lab grown diamonds share the identical optical, physical, and chemical properties as mined diamonds, they are graded under the same rigorous international criteria. This center diamond is accompanied by third-party certification from the IGI or SGL, verifying its colorless grade, clarity parameters, and Excellent cut architecture.

The Setting

Engineered for security and visual fluidity, the setting uses an asymmetric bypass architecture where the ring’s shank ends terminate directly into structural claws. This integrated design envelops the heart-cut diamond, anchoring the broad lobes and protecting the vulnerable lower point without masking the stone’s outline.

Beneath the stone, the under-gallery reveals an open heart-shaped skeletal framework profile. This open architectural geometry allows maximum light penetration from all side angles, directing light up through the pavilion and table facets to enhance brilliance while maintaining a low-profile, snag-free setting.

Metals and Finish

This piece is built by default in solid 14K gold (585 purity code), offering an optimal industrial balance between rich precious metal content and structural longevity for daily wear. The ring is finished with a flawless high-polish surface that accentuates the flowing curves of the bypass shank.

For alternative preferences, the setting can be executed across all three classic gold tones—warm yellow gold, clean rhodium-plated white gold, or contemporary rose gold—ensuring structural integrity that resists deformation over decades of active wear.

Customisation and Origin

Every ring is built entirely made-to-order, mapped precisely to standard international quarter and half-size charts. Following checkout on primiraluxury.com, our Surat team contacts you within 24 hours via WhatsApp and email to confirm your exact technical specifications before production begins. During this 24-hour window, you can customize the center stone carat tier, adjust the color and clarity grades, select an alternative metal tier (from 10K gold up to dense 950 platinum), or specify custom band widths and finishes.

Standard production requires 15–35 business days, which accounts for precision setting, sizing, and independent third-party laboratory certification. The low-profile, flowing contours of the bypass shank make this ring sit incredibly comfortably against the skin, making it an excellent choice for an active lifestyle where an engagement or fashion ring needs to transition smoothly from professional settings to weekend wear without catching. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.

Optional FAQ Block

Q: Can I choose between a CVD or HPHT diamond for this heart solitaire?

A: Yes. Our standard stock consists of high-grade CVD and HPHT stones within the D-F colorless range and VVS1-VS2 eye-clean clarity tiers. During your 24-hour post-purchase WhatsApp specification confirmation, you can express a preference for a specific growth method, and our sorting team will select the stone that matches your choice.

Q: How do I verify the authenticity of the lab grown diamond?

A: Every center stone comes with an independent IGI or SGL certification report. The loose diamond undergoes grading before being set, and its unique report number is laser-inscribed directly onto the stone’s girdle, which can be instantly verified on the official registry website (such as igi.org).

Q: Can this bypass ring be made to fit completely flush with a wedding band?

A: The fluid curves of an asymmetric bypass shank naturally curve around the finger, which means standard straight wedding bands will not sit flush. However, during our post-purchase CAD design phase, our workshop can create a matching curved or contoured shadow band designed to nestle perfectly against this specific ring’s bypass profile.

Faq's

What are lab grown diamonds or lab created diamonds?

Lab-grown or lab-created diamonds are artificially produced in a laboratory, using advanced techniques that replicate the natural diamond formation process. They possess the same chemical, physical, and optical characteristics as mined diamonds. The two main methods are High Pressure, High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These diamonds offer an ethical and environmentally friendly alternative to traditional mining, avoiding the associated conflicts and ecological impacts
