Onyx is a form of chalcedony, which is a microcrystalline quartz formed in the gas cavities of lava. Its multi-layered structure is similar to that of agates. When the stone has a black base and a white upper layer, it's called onyx. (Black onyx is uniformly black chalcedony.) When the base is brown, it is called sardonyx while carnelian-onyx has a red base.
Much of what is referred to as "black onyx" is gray chalcedony that has been chemically treated to be a rich black. The gray stone can be saturated with a solution of cobalt chlorate and chlorammonium, or it can be immersed for a prolonged period in a sugar solution and then heated in sulphuric acid to carbonize the sugar.
Brazil supplies the best multicolored raw material, but onyx is found worldwide. Gray chalcedony is found in India and China.
