Diamond Buyers Guide

Diamond's Clarity

A diamond's clarity is measured by the existence, or absence, of visible flaws. Tiny surface blemishes or internal inclusions -- even those seen only under magnification with a jeweler's loupe -- can alter the brilliance of the diamond and, thus, effect its value.

Clarity levels begin with Flawless (F & IF) and move down to Very Very Slight (VVS1 & 2), Very Slight (VS1 & 2), Slightly Included (SI1 & 2), and Included (I1, 2 & 3).
