CLARITY
Diamond Clarity is a way to measure the level of tiny imperfections that exist within almost all diamonds except the very finest. Most imperfections within a quality diamond will remain microscopic because you rarely look into a diamond with a microscope, but if there are too many it can affect the diamond’s apparent color rating and the way light escapes to give the stone its brilliance.
To many, a diamond’s clarity is the easiest to understand and see visually what determines the rating. Gemologists may describe these imperfections as inclusions, blemishes or clarity characteristics.
