Black onyx has been prized since antiquity for its deep, opaque black color and smooth polished finish, historically valued as a protective stone associated with strength and grounding energy. The elongated marquise silhouette lends the stone a graceful, elegant shape, while the diamond set directly into its center creates a striking point of contrast and brilliance against the deep black surface. The milgrain detailing, a technique using tiny beaded metalwork to edge a setting, adds a delicate, vintage-inspired texture characteristic of mid-century design.

Its dramatic dark stone and sparkling center diamond make it an easy everyday statement as well as a thoughtful gift for an admirer of vintage design.
