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. The stone is most commonly used for jewellery.Black onyx was used for jewellery by many ancient cultures. It has been found in tombs in ancient Egypt, and onyx is mentioned in the Bible. The stone is believed by some to relieve stress and enhance self-control.
This stone requires special care - exposure to water and other chemicals, such as lotions or perfumes, will damage it over time. If you polish the jewellery, avoid polishing the stone itself. A silver-cleaning dip should never be used with this piece.
