THE MATERIAL LIBRARY
Amazonite
A blue-green variety of microcline feldspar.
Colors & patterns
Blue-green to green, often with pale streaks or mottling.
Typical origins
Sources include Brazil, Madagascar, Russia, and Colorado and Virginia in the United States.
Hardness
6–6.5 on the Mohs scale.
Choosing & setting this material
White intergrowths give each cab its character. Feldspar cleavage makes protection from knocks important; pendants and earrings are good choices.
Care & cleaning
Clean gently with lukewarm water, a little mild soap and a soft cloth, then dry. Avoid steam, ultrasonic cleaners, harsh chemicals and sudden temperature changes, especially when treatments are unknown.
Origins above describe typical sources of the material, not the origin of an illustrated or stocked stone. Hardness measures scratch resistance, not resistance to breaking. Confirm the identity and treatments of the actual piece.
