I have returned 3 class rings. My mom doesn't even know where she lost it. So... that made it worse.

The child's ring may have actually been a lady's ring although jewelry was popular to buy infants at that time. Women were very tiny then, and their fingers very slender. So perhaps it may have been a woman's?

The Claddagh ring can be bought all over so perhaps it wasn't a good one? See one can hope! A true one is gold. Why did the Claddagh ring make you feel worse? Out of curiosity.
