Not long after my gemstone book was published, I was contacted by a prospector who found some diamonds in North Carolina based on this and another book I wrote in 1998 on diamonds in the US. So, get a copy and get out looking for some gemstones!
Others found several precious opals and some fire opal and another reported a new sapphire deposit. Others sent letters, email, and photos of the spectrolites and moonstones found because of my book - and these are just a few of the people who are out there prospecting and using my book. So, get a copy, and get out there and look for some gemstones - there are many, many deposits in Wyoming and nearby. Even some giant iolite gem deposits that remain mostly unexplored.
|Diamonds are isometric (equal-dimensional) |
and typically have crystal habits of a
octahedron or some modified version.
When I was at the University of Wyoming, periodically, people would call to ask about diamonds they found. One prospector called me from Jeffrey City, Wyoming to ask about the hundreds of diamonds he was finding nearby.
|Some of the common indicator minerals associated with |
diamond include pyrope garnet, chromian diopside, olivine
and a few other minerals. Note all of these that I collected in
Wyoming are gem-quality.
