Cookson Family Unearths 2.79-Carat Brown Diamond
COOKSON, Okla. — On September 13, 2025, Raynae Madison and her family traveled from Cookson to Crater of Diamonds State Park in Murfreesboro, Arkansas, to celebrate her nephew’s birthday. What started as a weekend trip turned into a rare discovery when they found a 2.79-carat brown diamond.
They named the gem the “William Diamond” in honor of her nephew. Park staff confirmed it is the third-largest diamond officially registered at the park in 2025.
How It Was Found
The family searched the 37.5-acre plowed field at the park, a public area where visitors can dig and sift dirt.
They found the stone on the northern side of the park, after digging through a few buckets and using sand-sifting tools. At first, Raynae thought it looked unusual but didn’t think it was a diamond.
When she showed it to her family, they brought it to the Diamond Discovery Center, where employees examined and registered it.
What Makes Brown Diamonds Unique
Brown diamonds from Crater of Diamonds often feature structural defects known as plastic deformation. These defects alter how light reflects inside the stone, giving them their brown color.
Despite the color, these diamonds still hold gem value and are cherished for their rarity and character.
As of this year, the park has registered more than 350 diamonds.
