Fluellite found 2001 - Sold

Fluellite is a fluorinated hydrous aluminum phosphate. Lévy (1824) named fluellite by combining Latin roots fluate and alumine, for fluorine and aluminum respectively, while not recognizing its phosphate content. Crystal structure analysis by Guy & Jeffrey (1966) demonstrated essential phosphate, thereby establishing its current chemical formula. Micro-crystals of fluellite occur in many localities, but the Willard mine is notable for its exceptional crystal size. Volume 4 of The Handbook of Mineralogy gives a maximal crystal size of 7 mm for the species.

This specimen is has a thick coverage of blocky fluellite crystals to 6 mm. The crystals are translucent and pearly. Good example! The matrix is impure limestone; its backside of the specimen has been sawn. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. Laskowski self-collected this specimen August 22, 2001.
