Physical properties

Formation & geological history

Formed in granitic pegmatites, hydrothermal veins, and schists. It is a variety of microcline feldspar that owes its color to traces of lead and water within the crystal lattice.

Uses & applications

Used primarily as a gemstone for jewelry (cabochons, beads), decorative carvings, and as a collector's mineral specimen.

Geological facts

Named after the Amazon River, although it is not actually found there. It is sometimes called the 'Hope Stone' in metaphysical circles. The most famous specimens often come with smoky quartz crystals.

Field identification & locations

Identify by its distinct turquoise-green color and 'perthitic' texture (fine white streaks or patterns). Commonly found in Russia, Brazil, Ethiopia, and the Pikes Peak area of Colorado, USA.
