Formation & geological history

Formed in granitic pegmatites and hydrothermal veins through slow cooling of magma. Its distinct color is caused by trace amounts of lead and water within the feldspar structure.

Uses & applications

Mainly used as a gemstone for jewelry, ornamental carvings, and a popular collector specimen.

Geological facts

Named after the Amazon River, although ironically it has not been found there. It is often called the 'Hope Stone' in metaphysical circles. Leading sources include Russia, Colorado (USA), and Madagascar.

Field identification & locations

Identify by its distinct blue-green color and 'Schiller effect' (pearly luster). Often found associated with smoky quartz or white feldspar in granite mines.
