About Red Diamonds
Red diamonds get their color from the presence of a rare crystal distortion called plastic deformation, which causes the diamond to absorb green light and reflect red light, resulting in the beautiful red color.
The color of natural red diamonds can range from pinkish-red to deep blood red. The more intense and pure the red color of the diamond, the more valuable it is. Red diamonds are often cut in fancy shapes, such as pear, cushion, and radiant cuts, to showcase their unique color and maximize their beauty.
