DIAMOND CLARITY
WHAT IS DIAMONDS CLARITY?
WHAT EFFECTS DIAMOND CLARITY?

INCLUSIONS
Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions.’ Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader. This is why expert and accurate assessment of diamond clarity is extremely important.
