This is one of the finest Spanish sphalerites our buying team has ever seen! The Spanish mines are finished, meaning only old rough or gems from an old collection can step in to fill the demand from collectors worldwide. This 216.90 carat super gem is custom cut in a modified, radiant emerald cut that was done by a master lapidary. When you see this glowing gemstone in person it will simply take your breath away, like it did ours!
This magnificent sphalerite was fashioned by master lapidary Egor Gavrilenko, who specializes in cutting gem quality Spanish sphalerite, a rare gem prized for its exceptional optical characteristics. Mr. Gavrilenko has been fascinated with geology and mineralogy since he was a child growing up in Saint Petersburg, Russia. Surrounded by mineral crystals brought home by his geologist father, Egor turned his childhood passion into a successful career as he began working in the gem testing laboratory of the Spanish Gemological Institute (IGE) and later as a mineralogist and lecturer at the Spanish Open University (UNED). Today, he is the IGE delegate to the Federation for European Education of Gemology (FEEG), holding the position of Vice Chairman since 2012. In 2007, Egor returned to his passion of lapidary work, concentrating primarily on precision faceting, developing new faceting designs and optimizing existing designs with the aid of computer technology. Egor's desire is for every gem lover to be aware of the incredible optical properties of Spanish sphalerite, made even more dazzling by his expert faceting!

With greater dispersion than diamond, sphalerite is an intriguing, yet challenging, gem. Known primarily to collectors for its lack of hardness, sphalerite can try the patience of even the most highly skilled lapidaries who dare to fashion it into a finished gem. Not only is it extremely soft, it also has perfect cleavage in six directions, making it extremely difficult to cut and polish! Add in the fact that it's a brittle gem, and you have an idea of the challenge that awaits its potential cutter. When a talented lapidary can complete the task of fashioning a gem, the results are more than worth the lapidary's efforts!
