Collection: Black Onyx

Black Onyx is a sleek, jet-black variety of chalcedony prized for its smooth polish and dramatic, timeless look.  Natural onyx is found in several parts of the world, including Brazil, India, Mexico and the United States. Much of the black onyx used in jewelry is treated or dyed to achieve its deep, even color, then shaped, polished and set into sterling silver or other metals.
