7.1" Wide, Purple Amethyst Geode With Calcite - Uruguay

This is a 7.1" wide, purple amethyst geode from the famous mines near Artigas, Uruguay. In addition to the amethyst, this geode contains large whit calcite crystals. The surrounding basalt (volcanic rock) has been shaped so that it displays nicely on a flat surface. A really attractive amethyst piece.

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.
