Clarity is a term used to describe the absence or presence of flaws (blemishes or inclusions) inside or on the surface of a diamond. Inclusions (inside the diamond) may include crystals, fractures, clouds, and cavities. Surface blemishes may include scratches, nicks, pits, abraded facet edges, extra facets and naturals.
