Diamonds 101: Clarity

Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a diamonds clarity grade and affect its cost.

One unique advantage of the Ideal Cut is that its sparkle can mask otherwise noticeable inclusions.
