It's traditional to wait for your seventh anniversary to celebrate with copper, but we're so smitten with the metal that we're going to jump the gun. Don't get us wrong, we're not cheating on gold and silver--they both have their place in the instant-glamour ranks. And nothing beats brass for that vintage feel. But there's something effortlessly cool and mystical about copper--what other metal can you think of that looks even better as it ages? Yes, a little bit of patina will go a long way in your home--from Terrain's handmade Prism Lamp, whose dimensional design balances glass with just a touch of burnished shine, to Tom Dixon's Hex Bowl, a serving piece that elevates your tabletop with a glimmering punch. The best part is, that much like fashion, there's no rule in interiors against mixing metals, so feel free to incorporate the shopping picks below with abandon.
