Amarillo Starlight

The Amarillo Starlight is the largest diamond found by a park visitor in the Crater of Diamonds State Park in Arkansas since 1972, when it was established as a state park. The Amarillo Starlight was found by W. W. Johnson of Amarillo, Texas in 1975 while he was vacationing at the park with his family. When unearthed, it was a 16.37 carat white diamond, but it has since been cut into a 7.54 carat marquise shape. Its value has been estimated between $150,000 and $175,000.
