Sparkle Plenty

A pink diamond weighing 24 carats sold for $46.2 million at auction in Geneva Monday. The buyer was jeweler Laurence Graff (also a noted art collector), who announced he was renaming the jewel “The Graff Pink.”

Sotheby’s had given the gem something of the hard sell, dubbing it, before Mr. Graff had his turn, “an exceptionally rare and truly magnificent fancy intense pink diamond of the purest, vibrant hue.” The hype worked: The sale had the highest total of any jewelry auction ever, $105.1 million.
