Yesterday, I went to a gem and jewelry trade show. I made a few bucks selling old thin gold chains and a few pieces of broken gold jewelry. (Of course I bought more jewelry), but my point is that if you go to the right place you can make some money by selling old gold. my girlfriend had a lot more stuff to sell and made $700.) You do not get a good price at those home parties or at the mall. But if the International Gem and Jewelry Trade show is coming to near where you live, it's a good place to go. If you really want the money and are disciplined enough not to buy more jewelry, it's a good idea.
