Cause of the Red Color

Various impurities and elements are the causes for color in color diamonds. Red diamonds are similar to Pink diamonds in terms of the cause for the color. It is not completely clear what the cause is but it is believed that deformities in the crystal lattice is what creates the pink color, and in this case, red hue.

Its beauty and glamour, not to mention value, is nothing short of satisfactory.
