Big Yellow Rock To Fetch 10 Mil.

A vivid canary diamond, weighing 102.56 carats, is expected to bring around $10 million in a Hong Kong auction. Sotheby's says it's the largest fancy colored stone they've ever sold. Set with white diamonds, the pendent can be also worn as a brooch, which makes it practical, as well as slightly ostentatious. It's not exactly a triumph of the jeweler's art.
