The first diamond was found on August 8, 1906, by John Huddleston on his farm.
From about 1911 to 1950, diamonds were commercially mined on a small scale by various mining companies.
In the early 1950's, Mr. and Mrs. Howard Millar opened the mine to the public. It became a huge tourist attraction.
In 1972, the mine was sold to the state of Arkansas. It has been operated as a state park ever since. You can visit the Arkansas State Parks website.
