This oval high-dome black onyx cabochon is a great choice for adding depth and drama to custom jewelry designs. Use it to create a simple, single-stone pendant or ring, or combine it with stones of complementary colors for multi-stone 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.
