14-year-old Kalal Langford discovered a 7.44 carat diamond at the Crater of Diamonds State Park in Arkansas. Officials at the park say it's the seventh largest rock found since the park was established in 1972.

Craig Langford, Kalel's father, said they were only at the park for 30 minutes when his son made the discovery.
