This round high-dome black onyx cabochon is a great choice for adding depth and drama to custom jewelry designs. A staple color in jewelry designs that complements nearly any stone, this cab is ideal for one-of-a-kind pendant and bracelet designs. Premium high-dome cabochons are much more substantial and increase the profile of the stone in your design.
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 stones. It is a hard stone and takes a high polish; since ancient times, onyx has been a favorite stone for carving.
