1.46 ctw Lab Grown Diamond Oval Three-Stone Ring 14K Gold

The Stones

This classic trilogy architecture centers around an IGI-certified oval brilliant lab grown diamond weighing 0.66 carats, displaying an E-F color grade and eye-clean VS clarity. The center stone is engineered with a specialized faceting pattern designed to mitigate the central bow-tie effect typical of standard oval cuts. Flanking the center stone are two graduated side-stones: matched oval brilliant lab grown diamonds totaling 0.80 carats (approximately 0.40 carats each), holding identical E-F color and VS clarity profiles. Because lab grown diamonds share the same optical, physical, and chemical properties as mined diamonds, these stones deliver an identical refractive index (2.42) and crisp facet intersection. Every stone is independently graded, featuring a laser-inscribed report number on the girdle verifiable via the IGI registry.

The Setting

The structural architecture uses a shared-wire under-gallery basket configuration. A series of four low-profile white gold claws grip each stone’s girdle, anchoring the diamonds securely while remaining visually unobtrusive to avoid interrupting the stone outlines. The open, sweeping wire under-gallery is elevated above the shank to allow maximum light exposure to the pavilions and pavilions’ depth, maximizing light return through the crown facets. The interior prongs are shared structurally between the center and side baskets, minimizing metal bulk and bridging the three independent settings into a seamless, unified line.

Metals and Finish

The default setting profile is constructed in 14K Gold (585) Yellow, featuring rhodium-plated white gold prong heads to ensure a neutral backdrop that prevents warm metal reflections from tinting the colorless stones. The band features a classic D-shape profile that tapers slightly into split shoulders as it meets the outer basket supports. For alternative preferences, the ring can be ordered across our five-tier metal ecosystem: 950 Platinum for maximum prong security and density, 18K Gold (750) for a richer hue, 10K Gold (417) for active-lifestyle scratch resistance, or 925 Sterling Silver for fashion-forward wear. The default finish is high polish, but satin, brushed, matte, or hammered textures can be implemented during spec confirmation.

Customisation and Origin

Every ring is built to order based on your exact parameters. Standard center stone sizes can be scaled from 0.25ct up to 3.00ct+ on custom order, with color ranges available from D through I and clarities from VVS1 down to VS2. Following checkout on primiraluxury.com, our workshop contacts you within 24 hours via WhatsApp and email to confirm your exact specifications, including quarter or half ring sizes, band widths, and metal tones before production begins. Production requires 15–35 business days (up to 45 days in rare certification cases).

The low-profile basket design allows this trilogy layout to sit comfortably against the hand, making it low-snag enough for daily wear alongside a standard wedding band. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
