What Is Diamond Clarity?
Diamond clarity is a measure of the purity and rarity of the stone, graded by the visibility of these characteristics under 10-power magnification. A stone is graded as flawless if, under 10-power magnification, no inclusions (internal flaws) and no blemishes (external imperfections) are visible. At Tiffany, we only accept 0.04% of the world’s gem-grade diamonds.
Does Diamond Clarity Really Matter?
A diamond with a poor clarity grade has multiple inclusions, which directly affects sparkle. Because inclusions hinder the refraction and return of light, the lower the clarity grade, the cloudier the diamond will appear.
