|Diamond Clarity refers to the presence or absence of internal and external flaws and blemishes. Diamonds without any flaws and blemishes are rarer to find and more expensive. Most diamonds have some inclusions or blemishes. These are either natural (trace of other minerals) or occur while mining and cutting.
Each diamond can be put in one of the following clarity categories:
FL-IF: Flawless: No internal or external flaws. Internally Flawless: Extremely Rare and Beautiful. This grade is awarded to diamonds with no internal flaws and only minor external blemishes.
VVS1-2: Beautiful Brilliance. Very Very Slightly Imperfect - These stones have very, very small inclusions. VVS1 is better than VVS2.
VS1-2: Beauty with Value. Very Slightly Imperfect - These stones have very small inclusions. VS1 is better than VS2.
SI1-2: Exceptional Value. Slightly Imperfect - These stones have inclusions that may be visible with the naked eye. SI1 is better than SI2.
I1: These stones have inclusions ranging from eye visible to very easily seen to the naked eye.
I2-3: These stones visible inclusions and are of lowest grade. My Solitaire does not carry these diamonds.
There are many impurities that are on the surface of the diamond. External flaws are the result of wear and tear on the diamond or from damage caused during cutting.
These are any of the many impurities that reside solely in the interior of the diamond. There are many kinds of internal flaws such as clouds, black spots (carbon), fractures, etc.,
