When I was a young kid my parents took me to Crater of Diamonds State Park in Murfreesboro, AR. This is the worlds only diamond mine/field where you anyone is allowed to hunt for diamonds and keep what you find. I did actually find a small diamond that was worth about $300 which was a lot for a 13 year old. The great thing about finding your own stones is the satisfaction of uncovering a stone that has been in the making for the last million years or so. Today you can find precious stones without getting your hands dirty and find a great selection of diamond rings at reeds.com where they offer a great selection of diamonds in many different cuts and sizes for men and women.
