BOSTON — The Salvation Army says it found an unusual surprise inside one of its red donation kettles: a diamond engagement ring given by a widow in honor of her late husband.

The charity says the anonymous benefactor placed the diamond ring – valued at $1,850 – and her wedding band in one of the kettles placed outside Boston’s North Station last week.

It says the rings were accompanied by a note in which the woman said she hoped they would be sold and the money used to buy toys for needy children. She said her husband always had a giving spirit – especially at Christmastime.

Salvation Army Major David Davis said Monday the “loving and kind” donation warmed the hearts of bell-ringers and other volunteers.
