|Diamonds from an undisclosed location. Note the distinct modified octahedral crystal habit of three of the diamonds.|
|Cryptovolcanic structure near Douglas Creek in the Medicine Bow Mountains|
of Wyoming. This has been suggested to be an impact structure, but it
is more likely to be a kimberlite pipe.

|Another cryptovolcanic structure of unknown origin - kimberlite?|
|Two excellent quality diamonds found by prospector Paul Boden in 1977.|
These were recovered with gold in a long tom build on Cortez Creek in the
Medicine Bow Mountains not far from the above cryptovolcanic structures
|General map showing diamond mines and diamond anomalies in North America. It should be apparent there is|
considerable potential. Much of the high potential for commercial diamond deposits are areas known as cratons (from
Hausel, 2007, 2008).

|Another cryptovolcanic structure (circular depression) filled with water and surrounded by calcium-carbonate rich soil.|
The depression sits on granite in Colorado. So, is this a kimberlite, an impact depression, or just a lake?
