The Legacy Diamond Signet — Marquise brings fluid movement and quiet brilliance to the organic gold signet ring with diamond. Centered on a marquise-cut lab-grown diamond, the design flows with molten-like curves that catch the light from every angle. Its sculptural surface feels naturally shaped—modern yet timeless, bold yet effortless. Handcrafted to order in NYC from recycled 14k or 18k gold or 950 platinum.
