Physical properties
Hardness: 6-6.5 (Mohs scale), Color: Pale mint green with streaks of pinkish-beige and grey, Luster: Vitreous to pearly, Crystal structure: Triclinic and Hexagonal, Cleavage: Perfect in two directions.
Formation & geological history
Forms in granitic pegmatites through the slow cooling of igneous magma enriched with water and rare elements like Lead, which provides the green tint.
Uses & applications
Primarily used as a gemstone for lapidary work, jewelry, and metaphysical collecting. In mineral form, feldspars are used in glass and ceramic making.
Geological facts
The green color of Amazonite was long believed to be caused by copper, but modern research shows it is actually due to small amounts of lead and water within the feldspar lattice.
Field identification & locations
Identify by its characteristic pale green to blue-green color mixed with white or pink feldspar. Look for the 'schiller' effect or grid-like white streaks. Found commonly in Brazil, Russia, and Colorado, USA.
