Physical properties

Formation & geological history

Formed in hydrothermal veins and basaltic geodes. The purple color is caused by natural irradiation of trace iron impurities within the quartz lattice. This specimen has been mechanically shaped and polished into a sphere.

Uses & applications

Popular in the jewelry industry, metaphysical collecting, and as home decor. Frequently used for meditation aids and 'healing stone' collections.

Geological facts

Amethyst was once considered one of the 'Cardinal Gems' along with diamond, ruby, sapphire, and emerald until large deposits were found in Brazil. Its name comes from the Ancient Greek 'amethystos', meaning 'not intoxicated'.

Field identification & locations

Identified by its distinctive purple hue and hexagonal crystal properties. Commonly found in Brazil, Uruguay, and Zambia. This specific specimen is a 'polished sphere' or 'crystal ball' variety popular with hobbyists.
