The Silicates: The Feldspar Group
"A superb, textbook feldspar crystal. Not just is it big, but it is stark white, perched on a natural pedestal, and just an amazing display of perfection in symmetry in nature. Ex. Franz Saller Collection of Bavaria, Germany; probably purchased in the 1980s. The piece is pristine and complete-all-around - remarkably free of damage." Photographed by Rob Lavinsky iRocks.com.
