The back panel of Gresso edition phone is dipped in 18-karat gold whilst the luxurious case is made up of 200-year-old African Blackwood. If that's not enough, Swaroski crystals have been sprinkled on the back panel to give it the final touch. Its already on sale for a few weeks, the redesigned black model from Gresso costs between 3000 and 3500 US dollars.

Back to the diamond studded white iPhone, its black panel is embedded with a platinum Apple logo encrusted with 6.5-karat diamonds. To slip in your bunch of credit cards, a hand finished wallet made from real Ostrich foot is included in the standard package.
