Physical properties

Formation & geological history

Occurs primarily in granitic pegmatites and metamorphic rocks. Its green color is attributed to small amounts of lead and water within the feldspar structure. Formed in deep-seated plutonic environments.

Uses & applications

Primarily used as a gemstone for jewelry (beads, cabochons), ornamental carvings, and by mineral collectors. It is also believed by some to have metaphysical healing properties.

Geological facts

Named after the Amazon River, although ironically, no deposits have been found there. It was famously used by ancient Egyptians for jewelry and was found in King Tutankhamun's tomb.

Field identification & locations

Identified by its distinctive 'Amazon green' color and white marbling/streaking. Frequently found in regions like Pikes Peak, Colorado (USA), Brazil, and Russia. Collectors look for the characteristic grid-like patterns and schiller effect.
