Onyx is often mistakably categorized as an agate, but is actually a type of chalcedony that is formed within gaseous cavities in lava. It is a banded black (or dark brown) and white chalcedony that resembles agate, hence the confusion. 

Black onyx is most often a chemically-treated, dyed gray chalcedony, but it can rarely be found in nature as well.

Onyx occurs all over the world in countries like Afghanistan, Madagascar, Peru, India and the United States.
