Diamond's Polish
The definition of the Diamond Polish is simple the overall state of the surface of a diamond that has been finished. The rating for diamond polishing is placed based on the amount of polishing lines that can be seen. The lines are located there due to small diamond crystals which are stuck to the polishing wheels that are used by diamond cutters. This process is done after the cutting. The polish is very important because it determines the degree of light that can pass through a diamond. That is what is defined as the diamond brilliance. All lab certified diamonds report polish from a range of Poor-Excellent similar symmetry. The lower the polish gives a diamond less brilliance which decreases the value and desire of the stone. Below are the five ratings given to Diamond Polish.
Polish Ratings
Excellent and Very Good have no noticeable difference so when choosing a diamond, the customer can get away with polishing. But when you push down to Fair and Poor the polishing is very noticeable and should be avoided if your budget allows for it.
