Formation & geological history

Formed in plutonic rocks, primarily granitic pegmatites. The green color is attributed to small amounts of lead and water within the feldspar structure.

Uses & applications

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

Geological facts

Amazonite is named after the Amazon River, although it is not actually found there. It is often referred to as 'Amazon Stone'. The Pikes Peak area in Colorado is world-famous for its deep blue amazonite crystals.

Field identification & locations

Identify by its distinct greenish tint and typical white streaks (exsolution lamellae) of albite. Found in Brazil, Russia, Madagascar, and the USA (Colorado and Virginia).
