Formation & geological history

Formed in granitic pegmatites and hydrothermal veins. Its distinct color is attributed to the presence of lead and water within the feldspar structure during its formation.

Uses & applications

Primarily used as a gemstone for jewelry, carvings, and as a popular specimen for mineral collectors due to its vibrant color.

Geological facts

Named after the Amazon River, though it is not actually found there. It is often referred to as the 'Hope Stone' in metaphysical circles.

Field identification & locations

Identified by its signature shades of turquoise-green and its perthitic (grid-like) white streaking or 'schiller' effect typical of feldspars. Common in Colorado (USA), Brazil, and Russia.
