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.
