Wood and leather are so yesterday. What you really want is some genuine marble on your precious gadgets. At least that's the pitch from Native Union, which recently announced its Clic Marble iPhone 6 case, available in matte black or glossy white -- the latter consisting of the nice Carrara white marble from Italy. Don't be fooled by its simple look, as the company took a year and a half to figure out how to carefully slice marble at just 0.8mm thick, and then reinforce it with fiberglass to keep it flexible and shatter-resistant. The case does add 2mm of bulk onto your device, and it does ask for $80 in the US or £70 in the UK, but these are the kinds of sacrifices that some are willing to make in return for that cold luxurious feel.
