Officials from Goodwill Industries say the ring has been appraised at $17,600, making it the most expensive item ever donated to Goodwill Industries Keystone Area.
The ring was discovered by retired jewelry Barry Landis, who has sorted through donated jewelry in Goodwill's Harrisburg distribution center for the last two years. Most of it is costume jewelry, but the donated diamond shone through.
The ring has a two-carat European-cut diamond, surrounded 14 smaller diamonds.
Goodwill officials aren't sure why the ring ended up being donated. No one has come forward to claim it.
