I've found an old ring, it was my Great Great Grandmother's. I'm allowed to keep it.
Every time I pick it up, it goes hot! I thought I was imaging it at first, so picked it up a second time. It's burning hot. DH picked it up earlier, said stop being so ridiculous. He said it was normal temperature, if anything a bit cold 
What's going on? Can anyone logically explain a reason for this?
Our DC is just starting to speak and says a few words here and there. He can say "Ouch, burny!" (Taught by us to keep away from hot stuff). I curiously let him touch it and he shouted "Ouch! Burny".
