Formation & geological history
Forms in igneous rocks like granite and pegmatites. The green color is caused by the presence of small amounts of lead and water within the feldspar structure.
Uses & applications
Primarily used as a gemstone for jewelry, cabochons, beads, and as decorative carvings or ornamental stones.
Geological facts
Named after the Amazon River, though it is not actually found there; it was likely confused with another green stone. It is often called 'the Hope Stone' in metaphysical circles.
Field identification & locations
Identify by its distinctive blue-green color and 'perthitic texture' (whitish streaks or schiller). Commonly found in Brazil, Russia, Madagascar, and the USA (Colorado).
