Most notable for diamonds are Botswana, South Africa, Russia, Australia and Canada. In the US, diamonds and their host rocks have been found in many states. In particular, the Colorado-Wyoming State Line district south of Laramie, has been the most productive area for the number of diamonds in the US (>130,000 diamonds) followed by Murfreesboro, Arkansas. Diamonds are isometric and occur in many crystal habits including cubes, octahedrons and other forms. They are hard with greasy luster and often found in streams (specific gravity of 3.5), kimberlite, lamproite, lamprophyre and other rare rock types. The host rocks for diamond are rare.

Tips for finding it:

Tools needed: Shovel, maddox, 4 prong heavy pitch fork, 1/2" mesh screen, 1/4" mesh screen, stainless steel screen mesh (same size as window screens)... serruca, 5 gallon buckets, 55 gallon barrel - cut 1/3 away lengthwise (for washing).
PROBE: stainless steel "T" handle 3/8" dia with 5/8" diameter pointed tip.





Special skills needed: persistance/Luck




Identification tips: glassy somewhat metallic looking.




Additional helpful resources:
Diamonds are heavy and are found in gravel layers. Although, since the park was mined they can be anywhere. To increase chances you use the probe to locate a gravel pocket and dig to the gravel. Wash the gravel in the different size screens stacked one over the next smaller screen. Carefully look at the large screen as a 4 carat or larger diamond will be in that screen... Use a serruca (spelling?) - round screen made with stainless steel screen about the size of window screen to look through the gravel in the 1/4"mesh screen and gravel in the screen sized mesh. The park attendants will show you how to use the serruca. Go slow this is the most important step. After shaking the seruca flip it over in one motion and land on level ground. Not too hard... The diamonds will be on top.

1- DIAMONDS in Colorado & Wyoming. Start out by visiting the Great Diamond Hoax site at Diamond Peak in northwestern Colorado. In 1871, two prospectors salted a sandstone outcrop with several pounds of diamonds, rubies & sapphires & swindled Civil war generals, two presidential candidates, a congressman and other investors. More than 100 years later, I found the site with another geologist & panned out 4 diamonds, 17 rubies and 23 garnets left by the scam artists (find the approximate location by searching for ‘Diamond Field Draw, CO on Google Earth) (see: http://GemHunter.webs.com).

Next, select (CEDAR MOUNTAIN ,Wyoming on Google Earth). Butcherknife Draw is located to the northeast of Cedar Mountain and has dozens of anthills with fabulous Cape Ruby (garnet) & Cape Emerald (diopside) & diamond (http://gemstonehunter.blogspot.com/2008/12/cape-rubies-cape-emeralds-garnets.html).
Some of these gems are similar to those used to salt the Great Diamond Hoax area.

Finally, select VIRGINA-DALE, CO in Google Earth). This will take you right to the middle of the largest diamondiferous kimberlite district in the US and potentially one of the largest in the world. In 1960, kimberlite was accidentally discovered here, but it was not until 1975 that it was accidentally discovered by the USGS. During sample preparation, a carborundum grinding wheel was carved by tiny diamonds from a rock collected from one of the State Line kimberlites. Since then, more than 130,000 diamonds were recovered from microdiamonds to a 28.3 carat gemstone. The district has fabulous specimens of kimberlite along with gem-quality pyrope garnet (Cape Ruby) and gem-quality chromian diopside (Cape Emerald). In the last couple of years, I found another 200+ kimberlites in this region. Many appear like impact features. (see: http://discussionsondiamonds.blogspot.com).
