Formation & geological history
Amazonite is a variety of microcline feldspar formed in igneous rocks like granite and pegmatite through hydrothermal activity or slow cooling of magma.
Uses & applications
Used primarily for balancing chakras in spiritual practices, as well as jewelry, cabochons, beads, and decorative ornamental carvings.
Geological facts
While named after the Amazon River, it is not actually found there; it was likely confused with other green stones found in the region. Its green color is attributed to the presence of lead and water within the feldspar structure.
Field identification & locations
Identify by its distinctive pastel green-blue color with white streaks or mottled patterns and its grid-like internal structure under light. Commonly found in Brazil, Colorado (USA), Madagascar, and Russia.
