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

Uses & applications
Used primarily as a gemstone in jewelry, for ornamental carvings, and as a sought-after collector mineral.
Geological facts
Despite its name, little to no amazonite is sourced from the Amazon River basin; the color comes from lead impurities.
Field identification & locations
