I was passed down a box of some pretty neat looking gems from my grandpa. They were tucked away and I’ve never seen or heard that he had any. Maybe it was just a little hobby collection.
I’m somewhat knowledgeable on precious metals, but I have no clue what I’m looking at when it comes to gems. Is this a cool little hobby collection or something I should keep in the safe?
I would like to learn whatever I can about them thanks!
