12 mm round cabochon forsetting or gluing
This gemstone with a flat base is made of Black Onyx.
Did you know?
Originates from the Greek "Onyx" meaning "nail or claw".
In Egypt, researchers discovered bowls entirely carved in onyx dating back to the IInd Dynasty. Also widely used by the Romans, this black stone has been in great demand for many centuries.
Black onyx stone is not originally black. It is treated by being immersed in a solution of black sugar and acid. The soft, porous nature of the stone allows the solution to soak in. After immersion, the stone is then heated. This is a common process that makes the color deeper and more lasting.
