Art Deco 10k Black Onyx/Diamond Masculine Signet Ring

In its original case for almost 100 years is one of my absolute favorite ring styles. This 1930’s Art Deco period 10k signet gents ring makes a rugged statement. With the black onyx face in perfect, no scratch, condition to the natural solitaire Diamond and the broad protruding shoulders it gives off a very masculine appearance. Size:11.5
