Polish refers to the degree of smoothness of each facet of a diamond as measured by a gemologist. Diamond polishing is an essential step in the process of producing brilliant, high-quality diamonds. Polish brings shine and beauty to the surface of a diamond. The price of a diamond depends on the cut, color, clarity, and carat as well as the polish. The polish of a diamond affects how well light can pass through the diamond. This is a very important feature in determining the overall luster of a diamond.
