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 colour deeper and longer lasting.
Please note that each stone is unique and can present differences of colors and sizes with the photo.
