Thus the diamond is placed with the beneath side going through up on white paper and examined by way of the bottom in standardized lighting.

Nearly all diamonds have nitrogen atoms dispersed throughout the stone and, because nitrogen absorbs blue gentle, this provides the diamond a yellow appearance.
