Physical properties

Formation & geological history

Formed in deep-seated igneous rocks like pegmatites, as well as hydrothermal veins. The color is thought to be derived from small amounts of lead and water within the feldspar structure.

Uses & applications

Primarily used as a gemstone for jewelry, cabochons, and beads. Also very popular as a pocket stone, in metaphysical collections, and as decorative carvings.

Geological facts

Amazonite was named after the Amazon River, although no deposits have actually been found there. It is the only green variety of microcline feldspar.

Field identification & locations

Identify by its distinct mint green to turquoise color and characteristic white streaks. It has two cleavage planes at nearly right angles. Found in Brazil, Russia, Madagascar, and the USA (Colorado).
