 | There is nothing quite like it. A diamond discovered in Arkansas is believed to be the most expensive diamond ever found in the U.S. 8.52 carats in it’s rough form, the icicle-like stone was then polished down to a 4.6-carat finished diamond. |
 | It’s believed to be the fourth largest finished American diamond. The diamond features a 147 facet, teardrop cut triolette shape, internally flawless, “D” colour. The diamond’s absence of nitrogen made it difficult to work with. Nitrogen not only turns a diamond yellow, it also makes it softer and easier to cut. |  |
 | “That diamond took over 100 hours to cut but then we had to do amelioration on the finish of the diamond and took another 80 hours so a total of 180 hours.” It is icicle-shaped, so he had to come up with a unique design to maximize the beauty of this particular diamond. He said the baseline value for the Esperanza is $200,000, but it could go much higher. |  |
 | The Crater of Diamonds is a 911 acre state park in Murfreesboro, Arkansas that contains a 37.5 acre plowed field in which visitors can literally dig for diamonds. It's the world's only diamond-bearing site that's accessible to the public. |  |
 | The largest diamond ever discovered in the US, the 40.23-carat Uncle Sam, was found there in 1924. It was cut twice, resulting in a final 12.42-carat (2.484 g) M-color, VVS1 clarity emerald-cut diamond. In 1971, the Uncle Sam was sold for $150,000. |  |
