Small round 4 mm cabochons - Black Onyx x5

Small round cabochons for gluing or setting, 4 mm.

Black onyx 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.
