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 — all black chalcedony on the market is grey chalcedony that has been chemically treated to achieve its characteristic deep, glossy black color. Black Onyx is the top-selling chalcedony in the market and has a long history of use in fine jewelry, including the bold geometric designs of the Art Deco era. These oval buff top double bevel cabochons feature uniform opaque black that makes them ideal for a wide range of jewelry settings.

  • Genuine black onyx (dyed black chalcedony)
  • Uniform opaque black color throughout
  • Buff top with double bevel profile
