Description
We are pleased to have purchased these two small Crandallite specimens sourced from the Little Green Monster Variscite Mine in Clay Canyon, Fairfield, Utah. Named in 1917 by Gerald F. Loughlin and Waldemar T. Schaller, Crandallite honors Milan Lucian Crandall, Jr., a mining engineer with the Knight Syndicate in Provo, Utah.
Crandallite displays a range of colors, including yellow, green, and brown, influenced by impurities, and typically exhibits a vitreous to resinous luster. While not as widely used as some gemstones, Crandallite finds application in lapidary work for small carvings or jewelry accents, owing to its distinctive colors. It also holds interest for mineral collectors.
The chemical formula for Crandallite is CaAl3(PO4)2(OH)5. It is commonly found in phosphate-rich deposits, often associated with other phosphate minerals. Besides Utah, Crandallite occurrences have been documented in various regions globally, including Brazil, the United States, and certain European countries.
