The Romans carved it into cameos, and most commercial black onyx on the market has been dyed for consistent color since naturally solid-black material is rare.

Black onyx has long been used in practices around a sense of groundedness when things feel uncertain, staying connected to your body and the moment, and settling into who you already are.
