Jean Schlumberger was one of the most renowned jewellery designers of the 20th century, and during his long and storied career, he created whimsical pieces for the likes of Elizabeth Taylor, Jacqueline Kennedy Onassis, and Greta Garbo. The Frenchman’s spirit lives on in the sparkling repertoire of Tiffany & Co., and a recreation of his Bird on a Rock brooch design is a prime specimen.
