Physical properties

Hardness: 6-6.5 (Amazonite), 7 (Quartz); Color: Pale green to turquoise with white and black/grey inclusions; Luster: Vitreous to pearly; Crystal structure: Triclinic (Amazonite), Hexagonal (Quartz)

Formation & geological history

Commonly formed in plutonic igneous rocks, especially granite pegmatites. The blue-green color of amazonite is attributed to trace amounts of lead and water within the feldspar structure.

Uses & applications

Primarily used as an ornamental stone, for lapidary work (towers, spheres, cabochons), and in spiritual/healing crystal collections.

Geological facts

Named after the Amazon River, though it is not actually found there. It was previously thought the color came from copper, but modern analysis confirmed it is due to lead impurities.

Field identification & locations

Identify by its distinct 'schiller' or grid-like white patterns (perthitic texture) and the presence of quartz inclusions. Often found in Minas Gerais, Brazil, and the Pikes Peak area of Colorado, USA.
