Black diamonds are genuine diamonds treated with radiation to make their color appear black. Under normal lighting conditions the color enhanced "black" diamond looks black. However, it is actually very dark green. To observe the very dark green color, a fiber-optic light source can be placed near a thin edge of the diamond (such as the girdle or culet). This allows the light to illuminate some of the interior of the stone. The very dark green color that becomes visible is commonly seen in enhanced black diamonds. The very dark green color that is seen is never seen in natural diamonds. It is a result of radiation treatment. Are there natural black diamonds that are not treated?
