I have old gold rings, necklaces, etc that I would like to sell. What is the best way to sell them? I see commercials on TV saying they will give cash for gold, but I feel strange sending gold through the mail to a company that I don't really know.

Also, what do I do with the semi precious stones in the rings? Do you normally just give the stones or ask them to take out and give you the stones back?

Thank you
