A 12 year old boy has unearthed a giant, honey-brown 5.16 carat diamond at Crater of Diamonds State Park in Arkansas. The diamond is apparently the 27th largest that has ever been discovered in the park by a visitor since it became a state park in 1972. The diamond is also the eighth largest brown diamond in the world. Officials at the park say that the rainy spring months have helped the diamonds appear on the grounds surface. Not only has this recent diamond been discovered, the largest diamond ever in the USA was also found on the same site in 1924 and weighs a huge 40.23 carats. If you fancy your chances at finding a diamond in the famous park, this large stone is the 328th to be found there so far this year. The park is also the eighth largest diamond producing site in the world, and with it being open to visitors your chances are defiantly high.
