Diamond Clarity

Diamond clarity is a degree of the purity and
diamond           rarity of the stone, graded by using the visibility of those characteristics below 10-strength magnification. A stone is graded as faultless if, underneath 10-energy magnification, no inclusions (inner flaws) and no blemishes (external imperfections) are seen. At Tiffany, we best be given .04% of the world’s gem-grade diamonds.

Tiffany Standard of Clarity
Tiffany’s strict diamond grading standards are performed with knowledge, integrity and accuracy. When Tiffany believes that a diamond’s clarity is at the borderline between grades, Tiffany will usually assign the stone a lower grade—by no means falsely inflating a diamond readability grade.

“If anything takes far from the beauty of the stone, we gained’t receive it.”
