15.2" Prasiolite (Green Quartz) Geode With Calcite - Uruguay

This is a rather unusual specimen of prasiolite (aka green quartz) from the amethyst mines near Artigas, Uruguay. It was mined from within a pocket in the basalt and features a secondary growth of sparkling clear quartz crystals with a large calcite crystal front and center. We can pretty much guarantee this incredible piece will look even better in person than in the photos.
