EFFENBERGERITE1

A dozen or more Effenbergerites were a new find at the Tucson Gem and Mineral Show in 2012. Prior to this find, large examples were micromounts. This piece is a huge example of this rare Barium copper Silicate, occuring in Sugilite. It's unusual to have such a rare mineral also have such a striking, attractive color.  It weighs 66 grams (about 2 ozs).
