17.3" Prasiolite (Green Quartz) Geode With Metal Stand - Uruguay

This is a rather unusual specimen of prasiolite (aka green quartz) from the amethyst mines near Artigas, Uruguay. It features not only a large "stalactite" crystal formation, but also a good sized calcite crystal. The edge of the "rind" have been polished to reveal more beauty. Sometimes referred to incorrectly as "green amethyst", it was mined from within a pocket in basalt rock. We can pretty much guarantee this incredible piece will look even better in person than in the photos.

Prasiolite is a green variety of quartz that only naturally occurs in a few locations. It is formed when amethyst bearing rocks are heated by nearby lava flows or intrusions. It's often marketed under the name, green amethyst though that is technically incorrect as by definition amethyst is purple in color.
