Woman Finds 3.69-Carat White Diamond at Arkansas State Park, Names It ‘Hallelujah Diamond’

— -- Susie Clark and her husband spent days hunting diamonds at Crater of Diamonds State Park in Murfreesboro, Arkansas, and on the last day she said a prayer.

“Are you going to bless me and let me find a diamond today?” Clark, from Evening Shade, Arkansas, prayed, according to a park news release.

Her prayer was answered shortly after with a 3.69-carat white diamond, which she saw “sticking out of a furrow ridge in the plowed dirt,” the release said.

Clark has named the teardrop-shaped rock “the Hallelujah Diamond” because it was an answer to her prayer, the release said.

Park Interpreter Waymon Cox described the stone as frosted white with a pearlescent shine.

According to the park, Clark’s find is the largest of this year, though other park-goers have found 121 other diamonds. A visitor found a 6.19-carat white diamond -- named the Limitless Diamond -- on April 16, 2014. Other diamonds of note found by the park’s visitors include a 16.37-carat white diamond and a 3.85-carat canary diamond.

Asked about the potential value of Clark’s diamond, Bill Henderson, the park’s assistant superintendent, said the woman would need to take the stone for independent appraisal.

Clark’s stone was large but did have inclusions, Henderson told ABC News on Monday. Some stones found at Crater of Diamonds have fetched high sums, including the canary yellow stone that 14-year-old Tana Clymer found in 2013. That diamond was sold for $20,000. A 3-carat stone found at the park in 1990 was eventually cut into a 1.09-carat brilliant shape. Graded as a flawless stone, it was mounted in a gold and platinum ring and sold to the state of Arkansas for $36,000, according the park’s website.

“The diamonds here are of high quality,” Henderson said, but added that each stone was different and needed be evaluated individually.

Clark had first visited the Crater of Diamonds State Park 33 years ago with her mother and grandmother from Germany. ABC News could not reach Clark for comment, but the release said that she plans to keep the diamond.

According to Cox, rainfall in recent weeks, combined with park staffers’ plowing the 37.5-acre search field -- eroded the surface of a diamond-bearing deposit, helping to bring more of the stones to the surface and increasing visitors’ chances of finding them.

“Diamonds are a bit heavy for their size, and they lack static electricity, so rainfall slides the dirt off diamonds that are on the surface of the search area, leaving them exposed. And when the sun comes out, they’ll sparkle and be noticed,” he said in the release.

Crater of Diamonds is the world’s only diamond-producing site that is open to the public, according to the park. Visitors who find diamonds are allowed to keep them.
