Having a special, albeit largely mysterious, story seems to have paid off in the case of a diamond discovered in a Shawnee Salvation Army kettle.

A ring featuring the diamond as its centerpiece sold Tuesday on eBay for $6,325, which is more than twice its retail value of $3,000. The money will benefit The Salvation Army.

Salvation Army volunteers found the .82-carat diamond, wrapped in paper, Nov. 30 while counting contents of the red kettle from the Shawnee Walmart that day. Meierotto Midwest Jewelers of Kansas City, Mo., appraised the European-cut diamond, estimated to be about 100 years old, and donated a ring setting so it could be auctioned ready-to-wear.

The weeklong auction ended at 10:15 a.m. The ring’s new owner is an unknown buyer with a shipping address in Indiana, according to The Salvation Army.

“What a wonderful ending to the story of this mystery diamond,” Major Charles Smith, divisional commander of The Salvation Army in Kansas City, said in a news release. “We hope it brings a lifetime of happiness to the person who purchased it.”
