Absolutely! Mixing your silver and gold jewelry together is a great look, and it allows you to wear more of your treasures more often. Lots of jewelry designers now mix gold and silver all the time. Look at David Yurman and Scott Kay. Beautiful stuff–all gold and silver combined! Try to keep the scale similar when you pile on the pieces–a fine chain will be lost when worn with a chunky one. Experiment–you may find you’re wearing your favorite pieces a lot more. And yes–you can mix fake and real–who can tell??
