Wyoming Diamonds. Diamonds were discovered in southeastern Wyoming in about 25 miles south of Laramie. Since then, more thandiamonds have been found in the Colorado-Wyoming State Line kimberlite district. These vary from microdiamonds to high-quality gems as large as a carat diamond from Colorado.

The Iron Mountain Kimberlite district is an unexplored diamond district. The geology and chemistry suggests that all of the kimberlites in the district are diamond bearing, yet only one small sample was ever taken from the region - and it produced a carat gemstone with several small microdiamonds.5/5.

Dan Hausel. Hundreds of kimberlites, lamproites, lamprophyres, diamonds and cryptovolcanic structures have been identified in the Wyoming Craton that lies under portions of Colorado, Kansas, Montana and Wyoming.

KIMBERLITIC DIATREMES IN NORTHERN COLORADO AND SOUTHERN WYOMING Two types of garnet lherzolites are found. One type, found in a satellite to the Sloan pipe, is characterized by clinopyroxenes with high Ca content (Ca/Ca + Mg = ) and by garnets with unusually low Cr, Ti and Ca content, termed group II garnets (Figs.
3 and 4). £ I Cited by: 3. One prospector reported he had found a large number of diamonds including one, flawless, 6-carat diamond, just by panning near the Sloan kimberlites in Colorado. Later, I was contacted by a prospector who found a cache of diamonds in North Carolina based on this and another book I wrote in on diamonds in the US.
