Antique Art Deco Onyx & Diamond Cocktail Ring 10k

This Art Deco cocktail ring features a rectangular black onyx slab with a circle of single cut diamonds at its center. The .03 total carat weight of diamonds shows a warm J color with VS2 clarity. The split shank design adds architectural detail to the 10 karat yellow gold band.
