A Christie's employee puts a late 18th century antique diamond brooch on display at the auction house in London. The brooch, believed to originate from the Boehmer and Baszanger necklace which Louis XV commissioned for his mistress Madame du Barry from the French Crown jewelers, is to be auctioned in the 'Jewels' sale on June 10 with an estimated price of $240,718 to $320,956.
