Kimberlite: Volcanic diamond bearing rock (also called blueground by the miners). These Kimberlite pipes are the primary source for diamonds. Open pit mines are started at the top of the pipe and vertical shafts are sunk down along the sides and then horizontal tunnels are then dug to access the pipe at greater depths. Kimberly Process: Also referred to as KPCS- Kimberley Process Certification Scheme. The Kimberley Process (KP) is a joint governments, industry and civil society initiative to stem the flow of conflict diamonds (rough diamonds used by rebel movements to finance wars against legitimate governments). The trade in these illicit stones has fuelled decades of devastating conflicts in countries such as Angola, Cote d'Ivoire, the Democratic Republic of the Congo and Sierra Leone. Knife-edge Girdle: A girdle of a diamond that is so thin that it can be likened to the edge of a sharp knife. This is a sign of poor cutting since such a girdle is easily chipped. Knot: An included diamond crystal that is encountered by the saw blade while the diamond rough is being sawn in half. Also an included diamond crystal that is encountered at the surface of a diamond during the polishing operation, and that stands out as a small, raised surface on the finished diamond. This is just like a knot in a piece of wood. |
