Obout Onyx: Black onyx is a type of chalcedony, which is a microcrystalline quartz formed in the gas cavities of lava. While natural black onyx exists, much of what's sold as "black onyx" is actually gray chalcedony that has been chemically treated to achieve a deep black color. The stone symbolizes protection, strength and perseverance.
