Of natural colored diamonds, green and red diamonds are by far the rarest body colors. The appearance of green in a diamond is caused by millions of years of exposure to a source of natural irradiation in the earth, either among uranium compounds or percolating ground water, which changes its specific absorption of light. The majority of naturally irradiated diamonds show isolated green strains that barely penetrate the surface of the crystal and are almost always removed during the cutting process. Conversely, a very small minority are exposed to the irradiation source over an extended period of time and therefore exhibit an even green hue throughout the entire crystal. Among this extremely select group of stones, only a very few have a true green color without any bluish, greyish or yellowish secondary colours. Natural, true green diamonds are therefore unique gemmological rarities, and represent an extraordinary group of beautiful and mysterious gems.
