Eight-year-old twins from Houston will return from their Spring Break trip to Arkansas with a valuable souvenir.
Grace and Garrett Duncan dug up a 2.5-carat light-brown diamond Sunday at Crater of Diamonds State Park.
The twins don't plan to have the diamond cut, but will leave it in its natural form, a triangular, almost heart shape.
They named it the Duncan Twins Diamond.
Grace says that she and her brother plan to show the diamond off to their third-grade classmates. Then it will go into a safe.
