This is a truly stunning specimen of rare, prasiolite (aka green quartz) from the amethyst mines near Artigas, Uruguay. Sometimes referred to incorrectly as "green amethyst" it was mined from within a pocket in the basalt and features "stalactites" with a secondary growth of sparkling, green quartz crystals. I can pretty much guarantee this incredible piece will look better in person than in the photos. Also be sure to check out the attached video.
The entire piece is 16" wide, 9.5" deep and stands 9" tall on the included, custom metal display stand.
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.
