Physical properties
Hardness of 6 on the Mohs scale with a vitreous luster. Features distinctive bright green to bluish-green color with white grid-like striations.
Formation & geological history
Forms in pegmatites and granitic rocks through hydrothermal processes, often crystallizing slowly from mineral-rich fluids at high temperatures.
Uses & applications
Widely used for ornamental carvings, polished cabochons, beaded jewelry, and mineral collecting.
Geological facts
The vibrant green-blue color is caused by trace amounts of lead and water within the feldspar structure. It is named after the Amazon River, though no deposits have been found there.
Field identification & locations
Identify by its unique turquoise-green hue mixed with white albite streaks. Commonly sourced from Russia, the USA, Brazil, and Madagascar.
