Product Details

Black Onyx, also known as black agate, is dyed black chalcedony. Chalcedony is composed of tiny crystals of quartz that are not visible to the naked eye. Natural black chalcedony is so rare that virtually all black chalcedony on the market is grey chalcedony that has been chemically treated to achieve its signature shiny black color. Black Onyx is the top-selling chalcedony in the jewelry market and was a staple material in Art Deco jewelry design. These cushion flat top single bevel stones feature a drilled hole and are offered in calibrated sizes, making them ideal for settings requiring consistent dimensions.
