Digging for Diamonds in AR: 7 Sustainable Ways to Dig

Most diamonds found here are small: the average since 1972 is about 0.21 carat (Arkansas Geological Survey). A number of stones over 5 carats have turned up, and the 40.23-carat Uncle Sam, found in 1924 before the park opened, is the largest diamond ever unearthed in the US (Arkansas State Parks). Importantly, their formation and depth mean these treasures have never seen harsh industrial mining; they maintain their natural state, color, and crystal structure.

How to dig for diamonds: three methods that work

The Arkansas Geological Survey describes three approaches used at the Crater, and which suits you depends on how long you can stay.

1. Surface walking. The most popular method, best after rain when erosion exposes stones. Walk slowly and pick up anything that reflects light; identify it later. The survey says most of the larger stones have been found this way.
2. Close search of a small square. Mark off a square yard, examine it at ground level, then move to the next square.
3. Digging, screening and washing. Experienced hunters dig to the gravel at the bottom of an old drainage, screen off large gravel, wash out the clay, then use a round-bottomed screen called a seruka to concentrate heavy minerals. The survey says these serious diggers find most of the small stones each year.

If you have only a day or two, the survey suggests the first two methods. If you have a week or more, wet screening is worth the effort.

What you are looking for: Arkansas crystals tend to look rounded, almost spherical, rather than sharp-edged, the survey notes. The average stone found since 1972 is about 0.21 carat, which is small. Colours are mostly white, brown and yellow (Geology.com).
