Onyx is a variety of chalcedony or microcrystalline quartz which is formed in the gas cavities of lava. Generally, most onyx has a parallel banding structure (as opposed to agate which is more irregular), however black onyx doesn’t tend to have this characteristic banding.

As a healing stone, black onyx is thought to increase regeneration, happiness, intuition and instincts.
