This Art Deco era cocktail ring features a .06 carat old European cut diamond (J color, SI2-I1 clarity) set alongside black onyx in a 14 karat white gold mounting. The rectangular design includes engraved borders and shoulders and geometric patterns popular during the Art Deco period. Black onyx provides contrast against the white gold and diamond in this two-stone arrangement. The ring shows some diamond abrasion consistent with its age and is sold in as-is condition.
