Over the past 30 years, hundreds of previously unrecorded gem occurrences were identified in Wyoming & nearby regions including diamond, ruby, sapphire, pyrope garnet, Cape Ruby, Cape Emerald, chromian diopside, peridot, opal, kyanite, gold, agate, jasper, iolite & others by using geological science & geochemistry. Two deposits of iolite are world-class deposits & one opal deposit is one of the largest in the world.
A good understanding of geology, persistence & some luck can lead to incredible treasures. In 1977, I started work as a research geologist at the Wyoming Geological Survey in Laramie. Next to nothing was known about gemstones in the state, but over the years, I tracked down many mineral deposits & found some of the largest gemstone deposits ever found on earth. Anyone can do it. My story is found in many publications, the most recent published by Booksurge at Amazon.
