Physical properties

Formation & geological history

Formed in granitic pegmatites and metamorphic rocks through hydrothermal processes. The green color is caused by trace amounts of lead and water within the feldspar structure.

Uses & applications

Primarily used as a gemstone for jewelry, ornamental carvings, and as a popular specimen for mineral collectors.

Geological facts

Known as the "Amazon Stone," it is named after the Amazon River, although no deposits have actually been found there. It was used by Ancient Egyptians for jewelry and amulets.

Field identification & locations
