Single blue and purple Tourmaline crystal from the Pederniera Mine. This crystal is from what I am told was called the 'blurple' pocket for the distincetive blue and purple coloration of the crystals. The crystal is zoned in approximate thirds, with a lower purple zone, a central blue zone, and back to a purple coloration at the termination. The crystal is gemmy, complete, and undamaged and weighs 16.79 grams.
