Physical properties

Hardness: 6-6.5; Color: turquoise, blue-green, or green, often with white streaks; Luster: Vitreous to pearly; Crystal structure: Triclinic; Cleavage: Perfect in two directions.

Formation & geological history

Forms primarily in granitic pegmatites and hydrothermal veins. Its distinct green color is caused by trace amounts of lead and water within its chemical structure.

Uses & applications

Widely used for ornamental carvings, beads, and cabochons for jewelry. It is also a popular specimen for mineral collectors.

Geological facts

Named after the Amazon River, though it is not actually found there. Most high-quality specimens come from Colorado, USA, or Madagascar. It is also known as the 'Stone of Courage' in metaphysical circles.

Field identification & locations

Identified by its distinctive blue-green color and 'perthitic' texture (white streaks or exsolution lamellae). Although it is found in the Appalachian region, this tumbled specimen was likely sourced commercially as it is not a common surface find in Maryland.
