Color refers to the natural tint inherent in white diamonds. In
nature, most white diamonds have a slight tint of yellow.
The closer to being “colorless” a diamond is, the rarer it is. The industry standard for grading color is to evaluate each stone against a master set and assign a letter grade from “D” (colorless) to “Z” (light yellow).
The most important of the 4Cs—cut—refers to how a diamond's facets
interact with light. It is determined by symmetry, proportion and polish.
More than any other factor, cut determines the beauty of the stone. Tiffany diamonds, from the smallest to the largest stone, are cut to exacting standards.

Diamond clarity is a measure of the purity and rarity of the
stone, graded by the visibility of these characteristics under 10-power
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.
