Formation & geological history

Formed in granitic pegmatites and metamorphic rocks. It crystallizes from mineral-rich hydrothermal fluids deep in the earth, often millions of years old.

Uses & applications

Primarily used as a gemstone for jewelry, carvings, and ornamental beads. It is a popular 'healing crystal' in the metaphysical industry.

Geological facts

Named after the Amazon River, though it is not actually found there. It was one of the first minerals used by ancient Egyptians for jewelry and amulets, often found in pharaoh's tombs.

Field identification & locations

Identify by its distinctive blue-green color and pale white streaks (exsolution lamellae), similar to marble. Commonly found in Brazil, Russia, Madagascar, and Pike's Peak, Colorado.
