What is Excellent polish?
Polish is the quality of a diamond’s finish or how smoothly the surface of a diamond has been polished. A diamond with Excellent polish has no polish defects visible at 10× magnification. Small surface defects, such as pits and polish lines, are often created by the polishing wheel during the polishing process and can usually be removed through re-polishing. While they are often invisible to the unaided eye, having a lot of surface defects will dim the shine and sparkle of the stone.
