Tiffany & Co. - Tiffany KeysCourtesy of Tiffany

Inspired by keys from the Tiffany & Co. archives, these gold, silver and platinum pendants had us at hello. There is a perfect-fit key for every wallet with prices ranging from $100 to $10,000. Our personal favorite is the Quatrefoil (middle, left) with its gold clover-like design and just the right touch of sparkle.
