21" Amethyst Geode Section with Calcite on Metal Stand - Uruguay

This is a huge amethyst geode section from the famous amethyst mines near Artigas, Uruguay. It's a gorgeous specimen with gemmy amethyst crystals that are relatively large. Each crystal has beautiful coloration across its termination that continues down each edge. There is a large, flat, amethyst encrusted calcite crystal that runs down the middle of this specimen, along with two stalactites at the top of the geode. The "rind" has been polished to reveal the underlying mineral layers. This specimen is a beauty and a beast, weighing in at just over 89 pounds including the stand!

The included custom metal display stand makes for a very aesthetic display.

While Brazil is a much more prolific producer of amethyst, the amethyst mined near Artigas, Uruguay tends to be much darker with higher quality crystals. We import our material directly from the mines in Uruguay, allowing us to offer it at better retail prices than anyone else. We carry a large variety of geodes, amethyst clusters, and collector quality crystal formations.

Amethyst is a purple variety of quartz (SiO2) that owes its violet color to natural irradiation, iron impurities, and the presence of trace elements, resulting in complex crystal lattice substitutions. It is considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires, and rubies. The largest and best known amethyst deposits occur in southern Brazil and Uruguay, but many localities around the world produce an amazing variety of amethyst crystals and formations.
