Onyx is a form of chalcedony. It is usually thought of as black or black and white, but it can be any color. Onyx is different than agate, which is also chalcedony, because onyx has parallel banding and agate doesn't.

This Black Onyx sphere measures 127mm in diameter, 2.55kg in weight, and even let's you see a bit of our little shop.
