The First Cartier Panther Jewelry Was Ordered By The Qajar Prince

  The sapphire clip brooch was sold at Sotheby's landmark sale of the Duchess of Windsor’s personal collection in 1987. Price realized? $1,026,667. At that same sale was the fully articulated onyx and diamond bracelet Cartier had created for her in 1952. It sold in 1987 for about $1.2 million and then reappeared at a Sothebys' sale in 2010 where it broke the record for any Cartier jewel—and any bracelet sold at auction—when the hammer went down at $4.4 million.
