Forms in granitic pegmatites, often found alongside quartz, albite, and other feldspars.
Uses & applications
Used primarily as a gemstone, carved into cabochons, beads, and ornamental objects. Popular among collectors.
Geological facts
The distinct blue-green color of amazonite is believed to be caused by small quantities of lead and water in the feldspar structure.
