Diamond Clarity

Diamonds completely free from internal flaws, or inclusions, are very rare and highly valued. Flawless Diamonds are treasured in the jewelry industry. Clarity is graded based on the number, location, size, and type of the inclusions found in a diamond. Kenny G and Company has some of the clearest diamonds available. Learn how to choose the best grade of clarity for your diamond at the best price.



FL, IF – Flawless: No internal or external flaws. Internally Flawless Diamonds: No internal flaws. Very rare and beautiful diamonds.

VVS1, VVS2 – Very, Very Slightly Included: Very difficult to see inclusions under 10x magnification. An excellent quality diamond.

VS1, VS2 – Very Slightly Included: Inclusions are not visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.
