America's Sweetheart, Julia Roberts plays hilariously against type in the delightful Mirror, Mirror. A wicked tool of her magic, this gorgeous necklace comes from one of the actress's favorite jewelry designers, Me & Ro. The gold and diamond piece shimmers and glows each time she works her witchcraft. I know it put a spell on me.
