Diamonds 101: Reference Guide
Diamond Clarity
When we speak of a diamond's clarity, we are referring to the presence of identifying characteristics on (blemishes) and within (inclusions) the stone.Inclusions, which are sometimes referred to as "nature's fingerprints", are usually not visible to the naked eye unless magnified. Inclusions are ranked on a scale of perfection known as clarity, which was established by the Gemological Institute of America (GIA). The clarity scale, ranging from FL(Flawless) to (I)Included, is based on the visibility of inclusions at a magnification of 10x. The position of inclusions can affect the value of a diamond. There are very few flawless diamonds found in nature, thus these diamonds are much more valuable.
