How about this for the ultimate stocking stuffer: a diamond-encrusted, one-of-a-kind iPhone worth $8 million? Stuart Hughes, the British jeweler that has made gem-strewn BlackBerrys, Bang & Olufsen sound systems and even a solid-gold Nintendo Wii, put this jaw-droppingly bling phone up for sale earlier this year complete with more than 500 diamonds and a platinum navigation button, which itself contains a 7.4-carat pink diamond. So who wound up buying it? Ridiculously wealthy Australian mining tycoon Tony Sage. No word yet on whether or not it drops calls.
