A staple color in jewelry designs that complements nearly any gemstone, this black oval onyx cabochon is ideal for adding depth and drama to custom designs. Set it in a bezel mounting to make a simple pendant or combine it with complementary-color gemstones to create complex necklace designs as well as matching sets including earrings and bracelets.Onyx, a type of opaque chalcedony, is naturally black and is generally dyed to achieve a more uniform color—it is the most common black gemstone and is popular for creating a striking centerpiece and for adding contrast to designs that include lighter and/or more colorful gems. It is a hard gemstone and takes a high polish; since ancient times, onyx has been a favorite for carving.
