Prior to 1975, only jade and a few agates were known in Wyoming. Central Wyoming was scoured by rockhounds searching for jade in the vicinity of Crooks Gap where impressive cobbles and boulders of very high-quality nephrite jade were found. But why were there no other gemstones in this state? The answer was simple: few rock hounds searched for other gems other than jade and agate, and geologists simply could not conceive of the idea that other gems were present. Even so, Dr. J.D. Love identified a few low quality corundum deposits that hinted at the possibility for ruby and sapphire in the state, and a specimen of high-quality precious opal from the Yellowstone region provided evidence for gemstones in that volcanic terrain. The nearby Absaroka volcanic mountains also provided geological evidence that both Yellowstone and the Absarokas likely contained significant gold, silver and copper deposits.
Within a few decades, Wyoming became known as the gem capital of North America. Many new rocks, gems and minerals were discovered by several rock hounds, prospectors and myself. Wyoming has an impressive list of gemstones and has the most diverse collection of documented gems of any state in the US or of any province in Canada.

I found minerals fascinating & identified several mineral species in Wyoming that had previously been unknown in the State.
After mapping the two largest diamondiferous kimberlite districts in the US, the largest lamproite field in North America & investigating a group of diamondiferous lamprophyres, I identified a few hundred cryptovolca
nic structures that are likely un
discovered diamond deposits in Colorado, Kansas, Montana and Wyoming, as well as in Canada and Africa. I was elated when I found the largest iolite gemstones on earth including stones >24,000 carats while leaving others in the outcrop that could top a million carats.
This led to the discovery of two of the largest colored gemstone deposits on the planet -Grizzly Creek and Sherman Mountains. I found giant opals weighing more than 70,000 carats & mapped what could be the largest opal deposit in North America due to a lead from a Riverton rock hound that covers parts of >14 sections of land. I found other gemstones and previously unrecognized minerals and rocks in Wyoming. Basically, these deposits potentially contain several hundred $billion in gemstones. All I did is I kept an open mind, used geology and geochemistry to find more deposits.
I love to write, so I published >650 professional and general interest papers
& geological maps & contributed to 30 books. I'm not even sure how many abstracts I submitted to professional and rock hound groups, but was a few hundred that were published in journals and newsletters - I just never kept track of these. Now, after 30 years of discovery, I decided to describe theses gems, minerals and rocks in Wyoming, where to find them, and provide insight on how to identify diamond deposits. Personally, I believe that one of the largest diamond fields on earth is found in the Colorado-Montana-Wyoming region and is awaiting prospectors & geologists to follow-up on these discoveries. I also found the largest iolite deposits on earth in Wyoming - and I found evidence for others. I found a half-dozen ruby deposits and evidence for many more, but could never get much support from the state. It was as if all of the rock hounds, prospectors and mineralogists were paying attention, but the State of Wyoming was hibernating and could not be bothered. But the heck with them - you can now stake your claim on my latest books - Gems, Minerals & Rocks of Wyoming - A Guide for Rock Hounds, Prospectors & Collectors and find out more about these gems, minerals and rocks at GEMHUNTER.

- After I had made discoveries of several colored gemstone deposits including ruby and sapphire deposits, I realized there was a close association of these aluminum-rich oxide gemstones with aluminum-rich rocks in Wyoming including vermiculite (glimmerite) and serpentinite. Using an old publication on vermiculite deposits of Wyoming, I made six additional discoveries within months of one another.
- Guide to the Mining Districts in the Medicine Bow Mountains (it is very unfortunate, but the US Forest Service followed discoveries in some major base and precious metal districts in the Medicine Bow and Sierra Madre Mountains withdrawing a couple of potentially world-class mineral districts for (1) massive sulfides (zinc, copper, lead, silver, gold) and (2) platinum-group metals).
