Elizabeth Taylor once called one of her large diamond rings her ice skating rink, I can't imagine what she'd make of the gargantuan gem above. The emerald cut diamond, which weighs 52.82 carats, will be auctioned as part of the Sotheby's Geneva Spring 2010 sale of Magnificent Jewels and Noble Jewels at the Beau-Rivage Hotel on May 11, 2010.

Other pieces up for sale include a pear-shaped fancy vivid blue diamond weighing 5.02 carats mounted in a ring aside a 5.42 carat white diamond and a cushion-shaped fancy intense blue diamond ring weighing 7.64 carats that has a presale estimate range of $4 million to $6 million.
