Physical properties

Formation & geological history

Primarily found in granitic pegmatites and hydrothermal veins. Its distinct color is attributed to the presence of lead and water within the feldspar structure during crystallization.

Uses & applications

Commonly used as a gemstone for jewelry (cabochons, beads), decorative carvings, and as a popular specimen for mineral collectors.

Geological facts

Named after the Amazon River, although no deposits have actually been found there. It is known as the 'Stone of Hope' and was used by ancient Egyptians for jewelry and amulets.

Field identification & locations

Identified by its distinct schiller (pearly luster) and white grid-like streaks or 'shiller' effect caused by exsolution lamellae. Found in Colorado (USA), Brazil, Russia, and Madagascar.
