Typical origins
Gem-quality material is found in Madagascar, Brazil and Mexico, among other locations.

Choosing & setting this material
Its vivid color makes an attractive focal stone, but it scratches more readily than quartz. Favor earrings, pendants or a protective setting.
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.
