TRUE GREEN
A true gemmological rarity, the unique appearance of greenin a diamond is caused by millions of years of exposure to a source of natural irradiation in the earth, which changes its specific absorption of light. The natural radiation would likely come from uranium in the rocks or percolating groundwater.
Often displaying secondary colours of yellow, blue or grey, it is extremely uncommon to find a gem that exhibits an even true green colour, and rarer to be polished into a circular-cut, as is the case with Lot 1631. In a special letter dated March 1, 2012, the GIA commented that "It is very unusual for coloured diamonds in general and even more so for Fancy Intense greens, to be cut as round brilliants. Indeed GIA has rarely come across the combination of Fancy Intense Green colour in a round brilliant..... The combination of its natural origin, saturated colour and cutting style makes this diamond an extremely unusual occurrence."
