MURFREESBORO, Ark. (KTHV) – The Crater of Diamonds State Park in Murfreesboro is holding a scavenger hunt of sorts on Earth Day this year.

Park officials say a cut and set .57-carat diamond engagement ring, set in white gold, will be the prize for one lucky miner at the Crater of Diamonds State Park.

The Diamond Lakes Diamond Ring Dig is set to begin at 8 a.m. on Saturday, April 22 and will continue until the prize is found or until the park closes at 5 p.m. If not found on April 22, the contest will continue until it is uncovered.

A decoy vessel, an engraved cut diamond-like glass, will be buried somewhere in the park’s 37.5 acre diamond search area. The first eligible participant to find it will receive the diamond ring, which is valued at $3,500 and was donated by Southern Specialties Fine Jewelry in Murfreesboro.

“This is an opportunity to introduce Crater of Diamonds State Park to people in Arkansas and throughout the region who may have never visited us before,” said James Howell, Crater of Diamonds Park Superintendent. “Having this event on Earth Day we believe will help generate an appreciation for this unique state park.”

Any alterations to the ring, such as resizing, are not included. The prize may not be substituted for another ring or monetary value.
