Black onyx is a deep black, opaque variety of chalcedony (a microcrystalline quartz), valued for its strength, protection symbolism, and versatility in jewelry, often created by treating naturally banded onyx or other chalcedonies to achieve a uniform black color, making it a durable stone.

Black onyx is found in many countries around the world, with major sources including Brazil, India, China, and Madagascar. Other locations where it can be found include the United States, Uruguay, Argentina, Canada, Germany, and the Czech Republic.
