Product Description
This lovely deep black cabochon has been cut from natural Black Onyx, dyed to create a uniform blackness, and then polished to a high shine.
Being a cabochon (often shortened to cab) means it is not faceted, and has a domed front surface and a flat back.
They can't be fired with the clay, so need to be set in a bezel. Make your own using fine silver bezel wire, or do it the easy way with a bezel cup. Our Bezel Cup Plain Round - Fine Silver - 8mm is perfect for this stone and can be set into metal clay and fired with the piece, creating a professional setting ready for you to put the stone in once the piece is fired and polished. Fix it in place by pushing the sides of the bezel around the stone with a Bezel Pusher.
This is a natural stone, it can contain inclusions and the colour and the exact size and height might vary from stone to stone. If you are planning to set as a pair, or need matching stones for any reason, please write us a little note and we will try to pick matching stones (as close as possible). The 8mm round cabs have a size tolerance of about 0.15-0.30mm (this is how much they can vary from stone to stone).
Dimensions: 8mm Diameter
