Who needs a diamond mine? Just visit Arkansas’ Crater of Diamonds State Park and, if you are lucky, there’ll be a diamond waiting for you in plain sight, says the Association of Mature American Citizens [AMAC]. That’s how Josh Lanik found his 2.2 carat gem. He was visiting with his family and told Park authorities: “We took the kids to look for amethyst on Canary Hill, and I was walking through an area where it looked like a lot of water had washed when I saw it.” The officials told him that the gemstone was the biggest diamond found so far this year. But the biggest diamond ever found at the Crater of diamonds is the legendary Uncle Sam diamond that weighed in at 44.23 carats when it was found in 1924.
