1.00ct Lab Grown Diamond Marquise Two-Tone Solitaire Ring

The Stone(s)

The focal point of this solitaire ring is an elongated marquise cut lab grown diamond, independently graded with an F color rank and VS1 clarity tier. This choice guarantees a completely eye-clean table and crisp, symmetrical crown facets that draw light efficiently through the stone’s sharp pointed apexes. Each stone is carefully selected to ensure optimal proportions that avoid the traditional shadow “bowtie” effect, presenting identical optical, physical, and chemical properties to mined diamonds. An IGI jewelry certification report number is laser-inscribed on the girdle, providing verifiable data searchable directly at igi.org.

The Setting

Engineered for structural security without sacrificing visual lightness, the setting architecture utilizes a two-tone execution. While the main band is rendered in warm gold, the setting head is configured in white gold to ensure no color bleeds into the F-grade colorless diamond. The engineering features four structural points of contact: two traditional low-profile side claws grip the center girdle, while specialized V-prongs cap and protect the fragile pointed tips of the marquise silhouette against daily impact. The setting is elevated on an open-wire cathedral gallery with a balanced structural bridge, allowing maximum ambient light to penetrate the stone from underneath, optimizing face-up brilliance.

Metals and Finish

This piece is built by default on 14K Gold (585 purity), delivering an ideal everyday balance of structural hardness and precious metal content. To accommodate individual style preferences and skin sensitivities, the ring can be ordered across five distinct metal tiers:

• 950 Platinum: 95% pure platinum, densest alloy, ultimate prong security, hypoallergenic.
• 18K Gold (750): Richer traditional hue, excellent structural integrity for complex settings.
• 14K Gold (585): Default standard, high scratch resistance and structural longevity.
• 10K Gold (417): Hardest gold alloy composition, maximizing durability for active lifestyles.
• 925 Sterling Silver: Premium anti-tarnish everyday fashion option.

The default finish is a flawless High Polish across the uniform round shank, though custom textures like Satin/Brushed, Matte, or Hammered can be selected during confirmation.

Customisation and Origin

Every ring is made-to-order to eliminate generic mass-production flaws. Within 24 hours of checkout on primiraluxury.com, our workshop team contacts you via WhatsApp and email to confirm exact specifications before production begins. During this consultation window, you can adjust the center stone carat tier (available from 0.25ct up to 3.00ct+), request alternative color/clarity ranges (D-I colors, VVS1-VS2 clarities), or alter the band width and ring size (including quarter and half sizes).

Production requires 15–35 business days to allow for precision setting, finishing, and independent laboratory certification processing. Standard domestic shipping within India is handled securely via Blue Dart or Delhivery (2–7 business days), while international orders ship fully insured and tracked via standard (17–19 business days) or express DHL/FedEx (5–7 business days, signature required). Craftsmanship errors, transit damage, or specification mismatches are protected by our strict 7-day return policy for unused items in original packaging.

This design features a remarkably slender band that pairs seamlessly flush against standard straight wedding bands, making it an ideal choice for an engagement ring that won’t require a curved contour band later. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.

OPTIONAL FAQ BLOCK

How does the two-tone setting protect the color appearance of the stone?

By placing the F-color colorless marquise stone in white gold prongs, we prevent the yellow gold of the main band from reflecting through the diamond’s facets. This ensures the stone retains its crisp, icy white appearance face-up while allowing you to enjoy the traditional warmth of a yellow gold band.

Why are V-prongs used on the tips of the marquise stone?

The pointed ends of a marquise cut are its most vulnerable points, where the diamond tapers thin. Traditional round claws can slip or leave the tips exposed to clipping. The structural V-shaped prongs enclose the apex completely, absorbing side impacts and preventing chipping during daily wear.

Can I choose a different center stone option at checkout?

Yes. Every Primira Luxury piece is built with a flexible variation model. At checkout, you can select between a certified lab grown diamond or a hand-faceted moissanite stone. Our moissanite options are cut explicitly by hand in our Surat facility to specific angles that control the stone’s high refractive index, avoiding the artificial effect common in machine-cut stones.
