Goldstriker International is a U.K. company that gives gadgets a luxury makeover. It collaborated with designer Stuart Hughes to make the iPhone 4 Supreme Diamond Rose, a gold phone that sold for $8 million. Only two were made, so the chance of finding one in your stocking is remote.
A more realistic option is the iPhone 4s 24ct Gold Ambassador Edition from Goldstriker, which was manufactured in a limited run of 100. Fully embellished in gold and with an outer frame inlaid with crystals, it sells for 2,995, or $4,825.
