To determine a diamond’s clarity, it is viewed under 10-power magnification by a trained eye. Most diamonds contain very tiny natural inclusions. However, 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 beautfiul the diamond will be. Diamonds, more than any other gemstone, have the capability to produce the maximum amount of brilliance. A diamond that is free of interior or exterior inclusions is very rare and therefore more valuable. So, the clearer the diamond, they clearer your choice.
