Amazonite

Physical Properties

Hardness: 6-6.5 on Mohs scale; Color: Greenish-blue, turquoise, or light green; Luster: Vitreous to pearly; Crystal structure: Triclinic; Cleavage: Perfect in two directions; Specific Gravity: 2.56-2.58.

Formation & Geological History

Formed in plutonic rocks, primarily granites and pegmatites, as potassium-rich fluids cool. Its characteristic color is caused by the presence of trace amounts of lead and water within the feldspar lattice.

Uses & Applications

Used primarily in jewelry as beads (like in the image), cabochons, and carvings. It is also a popular specimen for mineral collectors.

Geological Facts

Despite its name, amazonite is not actually found in the Amazon River; it was named after the region, but original discoveries likely confused it with other green stones. It is often called 'the Hope Stone' in metaphysical circles.

Field Identification & Locations

Identify by its unique blue-green color and 'schiller' or white streaks/mottling within the gem. It is commonly found in the Ilmensky Mountains (Russia), Colorado and Virginia (USA), and Madagascar.
