This Angelite comes from artisanal miners in Huancayo, Peru. The artisanal miners are digging near Casapalca Mine, an industrial pit mine. The large mine produces Zinc and other metals, as well as minerals such as Anhydrite. Angelite is a rare blue Anhydrite found in this area. Because it is a soft mineral, it is carefully mined by hand so that pieces can be polished into decorative collectables. It has a low environmental impact and is relatively low risk for miners.
