However, many people treasure bright and intense colored stones too.

Cut – This C is the most significant characteristic as worth and value of the stone is largely depended on it. The over all appearance and look gets enhanced with the efficient cut. Cut specifies the reflective qualities. In a well-cut diamond, light enters inside the stone from one facet and after covering all the sides, reflects back from the same facet to the eyes of the observer. This results in brilliant sparkle of light visible by the naked eyes of the spectator. When the stone is cut poorly then the light enters from one facet but instead of reflecting back it passes or leaks through the sides or the bottom of the stone.
