Background * History
- The name »Onyx« comes from the Greek word »Onux«, which means fingernail, referring to the translucence of the white-colored layer of the multi-layered stone. Onyx is a form of Chalcedony, which is Microcrystalline Quartz. It is formed in the gas cavities of lava. Onyx is black and white banded Agate. It should not to be confused with Onyx Marble, which is Limestone. Its multi-layering is similar to Agates. When the stone has a black base and a white upper layer, it’s called Onyx. When the base is brown, it is called Sard-Onyx and when the base is red it is called Carnelian.
