Lab Grown Diamond Marquise Solitaire Ring 14K Gold 1.21 CT

The Stone(s)

The focal point of this minimalist ring is a single, centrally positioned 1.21 carat Marquise cut laboratory-grown diamond. Measuring 8.30 x 5.50 x 3.55 mm, the gem exhibits exceptional optical symmetry with a balanced length-to-width ratio that forms a crisp, elongated outline without the dark center obstruction common in poorly proportioned cuts. Graded at an independent F color tier (colorless) and VVS2 clarity, the stone is entirely eye-clean under close magnification. The precise facet alignment yields high light-return, balancing fire and brightness across its points. This laboratory-grown diamond has the same optical, physical, and chemical properties as mined diamonds.

The Setting

The architecture relies on a specialized 4-prong peg-head setting designed specifically for elongated silhouettes. Four heavy-gauge spherical metal claws grip the stone’s critical boundaries—shielding the vulnerable pointed tips while anchoring the lateral facets safely. The gem is elevated above the band on an open wire-frame basket under-carriage. This structural design eliminates metal bulk directly beneath the pavilion, allowing complete lateral light entry from the sides and base to drive maximum scintillation. This elevated structure sits cleanly on the finger while maintaining a stable, low-center-of-gravity balance that prevents the ring from spinning.

Metals and Finish

Built with a gross weight of 3.81 grams and a solid metal mass of 3.57 grams, the band features a slender, uniform, high-polish comfort-fit shank. The default configuration is 14K gold (585 purity purity code), delivering an ideal everyday balance of pure gold content and structural rigidity. For alternative preferences, the piece can be ordered across five metal tiers: 10K gold (417) for active lifestyles, 18K gold (750) for richer metal saturation, or 950 Platinum (95% pure platinum) for ultimate prong security and a dense, hypoallergenic weight. All gold options are finished in high polish across yellow, rose, or rhodium-plated white gold tones.

Customisation and Origin

Every ring is built to order to match precise user parameters. Standard center-stone options span from 0.25ct up to 3.00ct+, alongside adjustments in color (D–I tiers) and clarity (VVS1–VS2 eye-clean stocks). The production timeline requires 15–35 business days (up to 45 days if complex third-party lab processing or custom sourcing is required). Within 24 hours of checkout, our workshop team will connect via WhatsApp and email to confirm exact specifications, including quarter- or half-size ring dimensions and band widths before manufacturing begins. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
