Physical properties
Hardness of 6 on the Mohs scale, vibrant green to blue-green color, vitreous luster, and triclinic crystal system.
Formation & geological history
Forms primarily in pegmatites and hydrothermal veins during the final stages of granitic magma crystallization.
Uses & applications
Used widely in ornamental carvings, cabochons, and bead jewelry, as well as valued by mineral collectors.
Geological facts
Its distinct blue-green color was traditionally attributed to copper, but modern research suggests it results from lead and water trapped in the crystal lattice.
Field identification & locations
Easily identified by its characteristic bright turquoise-green coloration and grid-like twinning patterns; commonly found in Colorado, Russia, and Brazil.
