The details
Black cushion onyx anchors this men's ring, a bold statement piece in polished two-tone gold with a natural round diamond beside it. The band is solid gold in a two-tone finish, and the polished surface lets the contrasting tones play against each other. The deep black onyx sits in a cushion shape while the faceted diamond adds a small, bright flash of light as your hand moves. Wear it with a crisp white shirt or a dark tailored jacket. A strong gift for a father or anyone who likes a ring with presence.
