Fabulous Green Emerald Makes It’s Debut at Basal Jewelry Show.

A dazzling 206.09-carat Colombian emerald of exceptional color and clarity, purchased by Bayco LLC from a private collector earlier this year made it’s debut this week at the Basal Jewelry Show in Basal, Switzerland.

The Imperial Emerald, 206.09 Carats

The polished cut yield from Emerald rough is in the range of 20-24% which means that The Imperial Emerald started out as a 800 carat rough stone, WOW!

Giacomo Hadjibay, a co-owner of the family-owned, New York-based jewelry company, said the gem, dubbed “The Imperial Emerald,” is the most exceptional stone their company has ever purchased.

The Imperial Emerald is the largest Emerald in terms of its clarity, color, brilliance and cut, and is untreated. It was mined at the Muzo mines, located at the foothills of the eastern range of the Andes mountains in Colombia which are known for producing the best emeralds in the world.

It was Colombian emeralds that the great Moguls of India coveted when they ruled the country, swapping their diamonds and gold with the Spanish for the green gems.

Bayco purchased this Emerald rough in 2012 and submitted it to three of the worlds best Gemstone Grading laboratories, the American Gem Laboratories, the Gemological Institute of America and Gübelin; who created books on the emerald, a step taken only for extremely rare and exceptional stones.

Bayco brought the stone to Baselworld to show it to the world, the first stop on what may be a global tour for the 200-carat-plus gem. .

Bayco is exhibiting at Baselworld, which began today and runs through May 2.
