Fluorite
description: <p style="text-align: justify;">LOCALITY: Afghanistan <br /><br />3 1/2" across <br /><br />This fluorite is from a granite pegmatite. Hence, it has been mined from a different geological setting than what most other fluorite specimens are mined from. Most fluorite specimens of the world are mined from limestone enclosed lead-zinc deposits which are also known as Mississippi Valley Type (MVT) deposits. Fluorite can also be deposited by hydrothermal activity. Localities that are MVT deposits with fluorite include Elmwood, Tennessee; Hardin County, Illinois and Berbes, Asturias Province, Spain. Fluorite found at the Sweet Home Mine, Colorado was deposited by hydrothermal activity. <br /><br />This particular fluorite specimen is particularly fine since the backside of the specimen is not cleaved. Hence, this fluorite specimen is free of damage. This is unusual for fluorite specimens removed from a hard rock granite pegmatite deposit. <br /><br />This piece was bought from Cal Graeber during a visit to his home in 2001 before the Tucson Show. <br /><br />Photo by Matthew Webb of Melbourne, Victoria, Australia <br /><br /></p>
