If you've got gold jewelry that you don't particularly like or wear, you can sell it for a little extra cash. How much you'll get will depend on the type of jewelry you have, how much gold it contains and who you sell it to. Regardless, you won't get the same amount you paid for the item, as these gold buyers are paying for only the gold, not the design of the jewelry or, in most cases, any gemstones it may contain.
