An uncommon treasure for gemstone collectors, sphalerite is a gem that has few peers in the realm of gemstones. With 3.5 times more dispersion than diamond, its fiery beauty makes it a gem in high demand with gem lovers across the globe. While prized by collectors, the availability of gem quality material is, at best, quite scarce. Historically, Spain has been regarded as the premier source for the finest quality gems. When fashioning rough material into gems, it is all about the lapidary and the cutting process. Sphalerite presents great challenges to the gem cutter due to its lack of hardness, perfect cleavage and brittle nature. Once a gem has been properly cut and polished, the final result is spectacular as the gems internal and external beauty has been revealed! Mother Nature wasn't shy as she was mixing sphalerite's formula. It is a zinc sulfide that contains varying amounts of iron, which determine its final color or mixture of color. Named from the Greek word "sphaleros," meaning deceptive, its name is well deserved as it presents identification difficulties in the field without proper gemological tools. A gem not often seen, we invite you to discover the brilliance of sphalerite today at Jewelry Television and jtv.com.
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 due to 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 that talented lapidary is, however, able to complete his task with a fashioned gem, the results are more than worth the lapidary's efforts!
