"I Found This Ring In My Backyard While Doing Gardening. After Cleaning It, It Doesn't Look Like A Normal Ring. Any Ideas ?"
Answer: "It's a Georgian/early Victorian mourning ring. The initials belong to the lost loved one. They were typically made from gold (18k+) and enameled in black. Yours looks like it was made around 1820s-40s."
The 25s would be nice
