The details
A black cushion onyx sits at the center of this men's onyx and diamond ring, a bold statement in polished yellow gold. The ring is made in solid yellow gold with a smooth polished finish that gives the dark stone a warm, glowing frame. A small round natural diamond adds a bright flash beside the onyx, and the band tapers so the top feels substantial while the back stays comfortable. You can wear it with a tailored suit for the office or with a white tee and dark denim on the weekend. It is a strong gift for a father or a graduate.
