Physical properties

Formation & geological history

Formed through hydrothermal or magmatic processes primarily in granitic pegmatites. The blue-green color is attributed to the presence of lead and water within the feldspar structure during crystallization.

Uses & applications

Primarily used as a gemstone for jewelry (beads, cabochons) and ornamental carvings. It is also a popular collector's mineral in its raw crystal form.

Geological facts

Formerly called 'Amazon stone,' it was named after the Amazon River, though no deposits have actually been found there. It has been used in jewelry since ancient Egypt, where it was often confused with turquoise or emerald.

Field identification & locations

Identify in the field by its distinct blue-green color and 'Schiller effect' (lustrous play of light on the surface). These beads show the typical mixture of blue Amazonite with reddish-brown jasper or iron staining. Common locations include Russia, Madagascar, Brazil, and the USA (Colorado/Virginia).
