Diamond Polish

The term "Polish" refers to the amount of polishing lines that are visible on the surface of a finished diamond. These polishing lines are caused by very small diamond crystals which are embedded in the polishing wheels used by diamond cutters to polish the surface of the diamond after cutting. Diamond polish is important because it can affect the degree to which light is able to pass through a diamond therefore making it more or less brilliant. Diamonds that are laboratory certified with a good, very good or excellent polish rating are the most desirable. Diamonds that have poor polish will be less brilliant and not as desirable.
