Lab Grown Diamond Oval & Round Toi et Moi Halo Open Ring (0.99 ctw) | Primira Luxury

The Stones

The defining asset of this asymmetric open bypass piece is its dual-center stone layout, pairing a 0.40 carat oval lab grown diamond alongside a 0.38 carat round brilliant cut lab grown diamond. Both center stones are selected at an E-F color grade and VS clarity tier, ensuring eye-clean interiors and excellent fire. Grounded in their specific optical geometry, the elongated facets of the oval stone complement the high light dispersion of the round brilliant cut. Encircling both main diamonds are 35 round brilliant accent stones totaling 0.21 carats, arranged in individual single halos. Every diamond used is a laboratory-grown stone sharing the exact optical, physical, and chemical properties of mined diamonds. Full IGI and SGL jewelry certification is available upon request, verifying all stone metrics independently.

The Setting

Engineered with an open bypass architecture, the ring positions the two distinct diamond heads side-by-side on the finger with a deliberate spatial gap. Each center stone is anchored within an elevated 4-prong claw configuration designed to maximize light entry through the pavilion facets. The under-gallery features an open-wire post architecture that lifts the dual micro-pavé halo frames above the finger line. This structural elevation allows light to pass upward through the accent settings, intensifying the overall light return without bulk. The micro-pavé borders are hand-set under magnification, ensuring each shared claw holds the accent stones securely along the perimeter.

Metals and Finish

This piece is built by default on a 14K rose gold (purity code 585) open-ended shank, providing structural integrity for the dual-head assembly. The warm copper tones of the 585 alloy saturate the metal backdrop, contrasting against the colorless E-F diamonds. For alternative preferences, the ring can be constructed across four additional metal tiers: 950 Platinum for maximum prong security, 18K gold (750) for an enriched hue, 10K gold (417) for active-lifestyle scratch resistance, or 925 Sterling Silver for fashion-focused wear. The shank is finished with a standard high-polish surface, though satin, brushed, or hammered textures are available upon request.
