Despite decades of research, scientists are still inconclusive as to the source of red color in diamonds. It is believed that the same cause of the pink color in pink diamonds is the origin of red color as well, but in a more concentrated dose. The most commonly accepted theory is that during the diamond’s formation, a plastic deformation is caused in the crystal lattice structure. Some of the atoms are misplaced as the diamond moves up through its kimberlite deposit, and the intense pressure of this movement causes the varying shades of pink, or red, to appear.[5] This lends credence to the hypothesis that red diamonds are in fact extremely dark pink diamonds, and why only one color intensity is possible. It is possible for red diamonds to be modified by the same secondary colors that can be found modifying pink diamonds as well.[6]
