Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone ring foundation in 18K yellow gold invites your choice of center stone, designed to showcase the distinctive marquise shape’s dramatic, vintage-inspired elegance.

Handcrafted in our Williamsburg studio, the band is forged from warm 18K yellow gold, polished to a soft glow that complements the diamond’s fiery facets. The three-stone setting balances presence with wearability, featuring a low-profile design that rests comfortably against the finger for everyday grace. Each prong is carefully shaped and inspected to ensure secure, precise mounting without excess bulk.

Our commitment to sustainability is reflected in the option for a lab-grown diamond center, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate architectural refinement paired with artisanal detail—its slender band and modest height make it ideal for stacking or wearing solo. The marquise’s elongated form visually lengthens the finger, enhancing elegance without overwhelming smaller hands.
