Carbonardo is a rare type of opaque black diamond used for drilling bits and abrasive wheels. Unlike other diamonds, carbonadoes are not found in a crystallized form - they are found in irregular or rounded fragments. These diamonds have a very hard polycrystalline carbon structure..
Today, it is also used in jewellery.
