How to Buy a Diamond: Clarity

Another important characteristic when evaluating diamonds is clarity. Clarity refers to the number, location, size and nature of inclusions that occur inside the diamond. The most pure of diamonds is the flawless, internally flawless and (VVS) very, very small inclusions. These diamonds command a very high price due to their rarity. Medium to very good clarity diamonds such as (SI) small inclusions or (VS) very small inclusions demonstrate the same degree of brilliance similar to a flawless diamond. Only a trained expert with a 10x loupe can examine and determine the exact clarity of these diamonds. If the inclusions are apparent to the naked eye, then the grade will be (I) or imperfect. Inclusions or blemishes give each diamond a distinct fingerprint that helps in making each diamond truly unique.
