I would like to acknowledge my old field partner, Wayne Sutherland, who provided considerable library research on this subject when I was at the Wyoming Geological Survey and spent time in the field searching for mineral deposits with me. We had a great time working together! We compiled a book on World Gemstones (Hausel, W.D., and Sutherland, W.M., 2006, World Gemstones: Geology, Mineralogy, Gemology & Exploration: WSGS Mineral Rept MR06-1, 363 pages). However, this book was never formally published because of concerns with the director; and I decided to leave the job I loved and take early retirement with a good conscience because of ethical and moral concerns. Still I was able to live my dream. Unfortunately, not everyone could make this decision and the survey lost nearly 40% of its staff and advisory board while two members passed away - Ray Harris and Bob Lyman. Both very good geologists and wonderful human beings.
