Diamond plotting is the process of recording a diamond’s inclusions. At the DCLA, diamond plotting is done on a computer diagram, which is then stored in a database together with all the measurements and features of a diamond. This database is similar to a finger print database, as all diamonds have unique inclusions. The diamond’s plotting is shown on the diamond certificate, and is very important in the identification of a diamond.
