Instagram photo taken by Andrew Prince Jewellery - The Duchess of Windsor's Cartier sapphire panther brooch. Many people have seen the front but few have seen the back, so here it is! Created in 1949, it sits on a 152.35ct Kashmir sapphire. She often wore it together with her blue chalcedony suite made by Suzanne Belperron. When it sold at the great auction in April 1987, it made $933,000.
