The Denver Art Museum had an exhibit called Brilliant: Cartier in the 20th Century which I was lucky enough to see in its last few days. This stunning emerald necklace was one of the highlights. The emerald is huge and almost translucent. Necklace worn by Countess of Granard. Cartier London, special order, 1932.
