Formation & geological history

Formed in plutonic rocks such as pegmatites and granites. 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, beads, and ornamental carvings such as this heart shape. Also popular among mineral collectors.

Geological facts

Also known as 'Amazon Stone', it was named after the Amazon River, although it is not actually found there; it was likely confused with other green stones found in that region.

Field identification & locations

Identify by its distinctive schiller or pearly sheen and white streaks (exsolution lamellae) of albite. Major deposits are found in Russia, Brazil, Ethiopia, and Colorado, USA.
