Crater of Diamonds State Park, Murfreesboro

#2 of 85 in Nature in Arkansas
Crater of Diamonds State Park is a 911acre Arkansas state park in Pike County, Arkansas, in the United States. The park features a 37.5-acre (15.2 ha) plowed field, the world's only diamond-bearing site accessible to the public. Diamonds have continuously been discovered in the field since 1906, including the Strawn-Wagner Diamond. The site became a state park in 1972 after the Arkansas Department of Parks and Tourism purchased the site from the Arkansas Diamond Company and Ozark Diamond Mines Corporation, who had operated the site as a tourist attraction previously.
In August 1906, John Huddleston found two strange crystals on the surface of his 243acre farm near Murfreesboro, Arkansas, and soon became known as the first person outside South Africa to find diamonds at their original source. The following month, Huddleston and his wife, Sarah, sold an option on the 243acre to a group of Little Rock investors headed by banker-attorney Samuel F. (Sam) Reyburn, who undertook a careful, deliberate test of the property.
After 1906, several attempts at commercial diamond mining failed. The only significant yields came from the original surface layer, where erosion over a long period of time had concentrated diamonds. In the early period, 1907–1932, yields from this "black gumbo" surface material often exceeded thirty carats per hundred loads (50 mg/Mg) (standard 1600-pound tramload of the early period). Highest yields from the undisturbed subsurface material (described as kimberlite or volcanic breccia by the U.S. Geological Survey) were two carats per hundred loads (3.5 mg/Mg) in 1908 and about two carats per hundred short tons (4.4 mg/Mg) in 1943−1944.

  • Four of us made the trip to the mine and had fun! The rentals were easy to come by and for.four people one kit was enough. Highly recommend doing a surface walk as well in case larger gems are on...  more »
  • Reasonably priced, nicely laid out, helpful staff, and clean restrooms. Didn't find any diamonds at the site but are taking home buckets of gravel to continue our search at home. Bring your tools...  more »
  • Fun day digging for diamonds... recommend bringing some kind of cover, this place is like the surface of the sun, it was 98° mid September... we used a 10 x 10 canopy and then attached a tarp on the side that we moved with the sun. You can take your own digging equipment or rent some there... remember whatever you take must be taken in by hand and hauled back out again.
  • Such a fun activity to do with friends and family and you never know you might find a real diamond. The facility is well maintained, there are people to guide you and identify the stones you collected. The field is pretty big and you can rent the equipments to dig and clean your treasure. Overall it was a good experience for $10 fee. Must have experience
