Physical properties

Hardness: 6-6.5 on Mohs scale; Color: Turquoise green to bluish-green; Luster: Vitreous to pearly; Crystal Structure: Triclinic; Cleavage: Perfect; Specific Gravity: 2.56-2.58

Formation & geological history

Formed in granitic pegmatites, hydrothermal veins, and schists. The teal 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, ornamental carvings, and 'crystal healing' practices; it is also a popular collector's specimen.

Geological facts

Historically called 'Amazon Stone,' though it is rarely found near the Amazon River; it was named as such because early explorers confused it with other green stones from the region.

Field identification & locations

Identified by its distinct blue-green color and white streaks/plagioclase inclusions. In the field, look for triclinic crystals in pegmatites in locations like Pikes Peak, Colorado, or Madagascar.
