12.2" Quartz/Amethyst Geode with Calcite Crystals on Metal Stand

This is a gorgeous druzy quartz and amethyst geode section from the famous amethyst mines near Artigas, Uruguay. Part of the "rind" has been polished to reveal the mineral formations underneath. The red color of the quartz can be attributed to hematite inclusions in the underlying layers. This specimen also features a cluster of several calcite crystals at its center, with additional calcites scattered throughout the druzy quartz.

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

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 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) 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.
