This is a gorgeous amethyst geode section from the famous amethyst mines near Artigas, Uruguay. The coloration of the amethyst is a beautiful purple hue and it comes with a custom metal display stand. There is a calcite crystal formation at the "bottom" of the geode cavity, portions of which contain quartz growth that encrusts the calcite.

The geode itself is 18.7" tall and it stands 25.2" tall on the stand.

While Brazil to the north 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 out 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) and owes its violet color to natural irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It’s 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 deposit occur in southern Brazil and Uruguay but many localities around the world produce an amazing variety of amethyst crystals and formations.
