Physical properties

Hardness: 6-6.5 on Mohs scale; Color: Turquoise-green to blue-green; Luster: Vitreous to pearly; Crystal Structure: Triclinic; Cleavage: Perfect in two directions; Specific Gravity: 2.55-2.57.

Formation & geological history

Forms in igneous rocks like granite and pegmatites through the slow cooling of magma. Its distinctive green color is caused by the presence of small amounts of lead and water within the feldspar structure.

Uses & applications

Predominantly used as a gemstone for jewelry (beads, cabochons), ornamental carvings, and a popular specimen for crystal collecting and metaphysical uses.

Geological facts

Named after the Amazon River, although no deposits have actually been found there; it was likely confused with other green stones. The finest specimens are often found associated with Smoky Quartz.

Field identification & locations

Identify by its unique blue-green 'schiller' or mottled white streaks (perthitic texture). Commonly found in Russia, Brazil, Ethiopia, and the Pikes Peak area of Colorado, USA. Noted for its tendency to crack under high heat.
