Black Onyx, also known as black agate, is dyed black chalcedony. Chalcedony is composed of tiny quartz crystals not visible to the naked eye. Natural black chalcedony is exceptionally rare — virtually all black chalcedony on the market is grey chalcedony that has been chemically treated to achieve its characteristic shiny black appearance. Black Onyx remains the top-selling chalcedony in the jewelry market and was widely featured in Art Deco jewelry design. This genuine black onyx cabochon features a flat top with a double bevel profile and includes a hole, making it suitable for a variety of jewelry and metalsmithing applications.
