Physical properties

Hardness: 6-6.5 (Mohs scale), Color: blue-green to turquoise with white streaks, Luster: Vitreous to pearly, Crystal Structure: Triclinic, Cleavage: Perfect at nearly 90 degrees

Formation & geological history

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

Uses & applications

Used primarily as a gemstone for jewelry (cabochons and beads), ornamental carvings, and as a popular mineral specimen for collectors.

Geological facts

Named after the Amazon River, though it is not actually found there. It is often called 'the Hope Stone' in metaphysical circles. The Pikes Peak area in Colorado is world-famous for producing amazonite with smoky quartz.

Field identification & locations

Identify in the field by its distinct blue-green color, feldspar-like cleavage planes, and 'schiller' or cross-hatch perthitic patterns. Commonly found in Brazil, Russia, Madagascar, and the USA (Colorado and Virginia).
