Physical properties

Formation & geological history

Formed in plutonic rocks such as pegmatites and granites through the cooling of magma. Its color is attributed to the presence of lead and water within the feldspar structure.

Uses & applications

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

Geological facts

Also known as Amazon Stone, it was once believed to come from the Amazon River, although no deposits exist there. It is actually found in Russia, Brazil, and Colorado, USA (notably the Pikes Peak area).

Field identification & locations

Identify by its distinct blue-green hue and 'schiller' or pearly sheen when rotated in light. Found commonly in regions with granitic pegmatites. Collectors look for intense color and blocky crystal shapes.
