Very nice, decorative rough piece from the Bandet Iron Mine in Griqualand - South Africa.
Falcon's eye is a fine-fibered quartz aggregate with crocidolite. The color varies from blue-green to blue-grey. Tiger's eye is formed from falcon's eye by the incorporation of limonite and silicification of crocidolite. BOTH varieties are present in this piece!
Excellent raw material for grinding and polishing.
