Kimberlite and Lamproite – Host Rocks for Diamond

Chuck Norris’s cousin, Vic, digs for hidden kimberlite under grassy vegetationanomaly discovered by the Gem Hunter in the Iron Mountain kimberlitedistrict in Wyoming. Kimberlite is very difficult to recognize. It is basically a potassic peridotite and comes in a variety of colors and textures. Most notable is green kimberlite due to abundant serpentinized olivine. It

How to Identify Diamonds in Nature

In addition to the type of diamond we see at weddings, other varieties of extremely hard natural carbon are known including carbonado (polycrystalline) and lonsdaleite (hexagonal). These are all forms of carbon, as is graphite. But carbonado and lonsdaleite are very rare

After I was hired

Geology of Gemstone Deposits

The chlorite slowly replacedthe garnet and accepted the garnet’s crystal form.  Much of Wyoming is underlain by Archean cratonic basement rocks and cratonized Proterozoic rocks that provide favorable geological environments for a variety of gemstones – notably diamond, iolite, ruby, sapphire, garnet, kyanite,
