Antique Art Deco Onyx & Diamond Cocktail Ring 14k

This Art Deco cocktail ring features a navette-shaped black onyx centerpiece with a single cut diamond set at the center. The H color diamond faces up near colorless to the eye, while the SI1 clarity means any inclusions are only visible under magnification. Intricate filigree work decorates the 14 karat white gold mounting, creating an openwork design characteristic of the 1920s-1930s era.

The elongated navette shape creates a flattering silhouette on the finger. The contrast between the jet black onyx and the white gold filigree gives this ring its distinctive Art Deco appeal.
