Cartier Jewelry :
In 1987, Sotheby’s famously auctioned the jewels of the Duchess of Windsor, including a Cartier single strand pearl and diamond necklace, originally belonging to Queen Mary, which sold for 733,333 USD. In 2007, the necklace returned to the auction block at Sotheby’s and nearly quintupled its price with the final hammer bid of 3.6 million USD
