In the elite world of fancy coloured diamonds, green and red are by far the rarest body colours. 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 colour without any bluish, greyish or yellowish secondary colours, as is the case with this diamond. Natural, true green diamonds are therefore unique gemmological rarities, and represent an extraordinary group of beautiful and mysterious gems.

The most famous of all green diamonds is the legendary ‘Green Dresden’, a modified pear-shaped bluish apple-green diamond of 41.10 carats. Only a handful of natural green diamonds have been auctioned in the past thirty years, and most of them exhibited either bluish or yellowish modifying hues. The largest and most valuable green diamond ever offered at auction was sold by Sotheby’s Geneva in November 2009, a cushion modified brilliant-cut fancy vivid green diamond weighing 2.52 carats (3,106,500CHF/ 3,078,914USD). This diamond, a cushion-shaped modified brilliant fancy vivid green diamond weighing 2.05, is sure to appeal to the most discerning fancy coloured diamond connoisseurs.
