Thanks to bbc.com I learned today of a large jewelry exhibition at the Musée des Arts Décoratifs in Paris. It includes 260 pieces by 150 artists, including Salvdor Dali, Man Ray, Alexander Calder and Pablo Picasso.
The exhibition opened March 7th and closes on July 8th. The Musée des Arts Décoratifs is in the same complex as the Louvre but is managed separately.
