Nature has identified each diamond by natural inclusions: crystals, feathers, lines, etc. These traits developed in the diamond during its formation.

Diamond clarity is determined by the visibility of these inclusions, viewed under 10-power magnification by a trained eye.

The fewer and smaller the inclusions are, the less likely it is that they will interfere with the passage of light through the diamond, and the more beautiful the diamond will be.

While most inclusions may not affect the beauty of a diamond, they do affect its value and price.

A diamond that is free of interior or exterior inclusions is very rare and therefore more valuable.
