Clarity measures the flawlessness of a diamond and correlates
directly to its value. A stone is said to be flawless if, under 10-power
magnification, no internal flaws (clouds, feathers, pinpoints) or
external imperfections (scratches, pits, nicks) are visible. Absolutely
flawless diamonds are exceedingly rare.
Gem-grade diamonds are given a clarity rating based on a scale that
is standard in the trade. However, when Tiffany believes that
a diamond’s clarity is on the borderline between two grades, Tiffany
will always give the stone the lower grade.
