One geologist spent 30 years exploring Wyoming while noting the variety of minerals, rocks and gemstones scattered statewide. During these investigations, Wyoming, which once was considered to be relatively poor in gemstones, soon became known as having the most diversified assemblage of gemstones of any state in the United States. The author discovered dozens of new mineral, gemstone and rock localities, more than a hundred gold anomalies and mapped the largest diamondiferous kimberlite fields in the US and the largest field of lamproites in North America. During these investigations, the author, W. Dan Hausel, discovered some of the largest gemstones and deposits on earth. Now he shares these localities with his readers.
