The details
A black oval onyx cabochon sits against polished yellow gold in this men's diamond onyx ring, a bold look with a quiet shine. The ring is solid gold, finished to a bright polish that gives the deep black stone a clean frame. Two small natural round diamonds add a subtle flicker beside the onyx, while the band tapers so the top feels broad and the back stays comfortable. You can wear it with a charcoal suit or a worn-in leather jacket and it holds its own either way. It makes a considered gift for a father or partner on a milestone day.
