These black onyx cabochons are a great choice for adding depth and drama to custom jewellery designs and jewellery pieces with protective settings that won’t expose the stone to a lot of wear and tear

Onyx, a type of opaque chalcedony, is naturally black and is generally dyed to achieve a more uniform colour—it is the most common black gemstone and is popular for creating a striking centrepiece and for adding contrast to designs that include lighter and/or more colourful stones. It is a hard stone and takes a high polish; since ancient times, onyx has been a favourite stone for carving.
