Marie Antoinette’s jewellery to be auctioned at Sotheby’s

At jewellery auctions, provenance always pushes demand – and prices – sky-high. Attribute a gemstone to the collection of a celebrated actress or socialite and it will most likely achieve far more than the standard cost-per-carat. So it’s difficult to put a price on a collection of jewellery owned by the last Queen of France, Marie-Antoinette, which is set to be auctioned in a landmark sale at Sotheby’s in Geneva this November.

The sale features over 100 jewels from the Bourbon-Parma royal family, many of which have never before been seen in public. Among them are several pieces from Marie-Antoinette’s personal collection.
