Description

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.
