A first-time visitor to Arkansas' Crater of Diamonds State Park turned to YouTube for help in finding a gleaming rock and, almost immediately, spotted one. After searching through the dirt for about an hour on a spur-of-the-moment family outing on Aug. 16, Miranda Hollingshead of Bogata, Texas, sat down in the shade to watch a YouTube video with tips on finding diamonds, per Arkansas State Parks. It was apparently effective. "When I looked down, I saw it mixed in with other rocks," the 27-year-old says of the largest registered diamond found at the park since March 2017: a 3.72-carat yellow rock.
Found at the base of a hill on the northeast side of the 37.5-acre search zone, in an area of unweathered volcanic rock, the diamond is "about the size of a pencil eraser" and looks something like "a rounded molar, with a small indentation in one end," says Waymon Cox, a park interpreter. The rock is rare in that just 10% of the park's diamonds are found on the surface of the ground, which is regularly plowed. Yellow diamonds are also found less often than white and brown ones. Hollingshead says she'll mount the diamond on a ring—unless she opts to sell it. Gizmodo reports "it's likely worth somewhere in the tens of thousands of dollars." (More diamond stories.)
