Green Onyx

Onyx, as a form of chalcedony, 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. When the base is brown, it is called sardonyx while carnelian-onyx has a red base.
