A 206 Carat Gem Quality Unenhanced Cushion Colombian Emerald.

Unveiled to the world at the Baselworld Exhibition on April 25, 2013, The Imperial Emerald is the rarest emerald to date and is one of the most precious gemstones to ever exist. A 206 carat gem quality unenhanced Colombian emerald is a true anomaly in nature.

Emeralds are sought-after gemstones, and have been throughout history; in fact a truly fine emerald may be more valuable than a diamond of the same size. These gems range in size from very small to very large, however the rarity of finding one of this magnitude is rather exceptional. Colombian emeralds set the highest standards of quality for all emeralds, which are differentiated from other stones by the quality of their color: a shining green without any bluish tint. They are also prized for their transparency, crystallization and fire. The green color that this gem possesses is generally considered more desirable and the slight natural mineral inclusions add to the stone’s character.

The Imperial Emerald has been praised with certificates containing extensive special comments by all the laboratories which certified it, including Gubelin, AGL, GIA, C Dunaigre Consulting, and GRS. It has also received a Gem Portrait by Gubelin, a JewelFolio by AGL, and Monograph by the GIA. Each of these is a detailed book made by each lab which is reserved only for extremely rare and exceptional stones.
