Physical properties
Hardness of 6 on the Mohs scale, vibrant turquoise to blue-green color, vitreous luster, and triclinic crystal system with good cleavage.

Forms mainly in pegmatites and granitic rocks through hydrothermal activity and slow cooling of magma over millions of years.
Uses & applications
Widely used in ornamental carvings, gemstone jewelry, and sought after by mineral collectors.
Geological facts
Its distinctive blue-green color was historically attributed to copper, but modern research shows it results from trapped lead and water molecules within the crystal lattice.
Field identification & locations
Identified by its characteristic bright green-blue shade and grid-like twinning patterns; commonly found in Brazil, the United States, Russia, and Madagascar.
