FLUORITE – THE COLLECTOR’S CHOICE. Mint condition. One of my favorite books from the monograph series from Lithographie, Inc. Some 120 pages with 23 chapters written by experts around the world. Chapters on mineralogy, geology, color, fluorescence, and famous locations in United States, Canada, Mexico, Russia, China, Japan, Pakistan, South Africa and Morocco. My favorite chapter is written by Ross Lillie on The Great Southern Illinois Fluorspar Deposits.
