  Onyx is a chalcedony quartz that is mined in Brazil, India, California and Uruguay. It has a fine texture and black color; when onyx has white bands or ribbons against a black or brown background it is known as sardonyx.
The name comes from the Greek word onyx which means nail of a finger or claw. This is from a myth in which Cupid cuts the fingernails of Venus and the cuttings turn into stone.
Most Black Onyx that is commercially available today is color enhanced (heated and dyed) to increase it's depth of color.
