Black onyx is a form of chalcedony, which is a variety of quartz. Black onyx or black agate is most commonly recognized as a solid black stone although it will often be mixed with white lines or banding running through it. This banding can create some unusual patterns within the stone.
Expert gem cutters carefully select the rock and cut to produce the stones with the best color patterns. Whether solid black or striped, the stone is prized for its pure black sheen and high polish.
Black Onyx assists in self control, decision-making and intuition. It is also a protective stone that absorbs negativity to promote emotional well-being, and may increase intelligence and spiritual inspiration.
