This Jewelry Book Highlights a Hot New Gemstone Exhibition
“Gems” is the fruit of a collaboration between Van Cleef & Arpels and the Muséum national d’Histoire naturelle in Paris.

Paris—A new jewelry book allows mineral lovers to enjoy a Parisian gemstone exhibition from home.
In honor of the “Gems” exhibition opening this month at the Muséum national d’Histoire naturelle, or National Museum of Natural History, in Paris, Rizzoli is releasing an accompanying tome of the same name.
The exhibition is the fruit of a collaboration between the museum and famed Place Vendôme jeweler Van Cleef & Arpels. It celebrates gemstones from mine to finished piece of jewelry, showing them at many stages in between.
More than 500 minerals, gems and objets d’art from the museum’s permanent collection will be on display alongside more than 200 Van Cleef & Arpels jewels, showcasing the many possibilities when stones are in the hands of expert designers and craftspeople.
The accompanying book, published by Flammarion (a Rizzoli publishing partner), is one part gemstone reference guide, one part jewelry catalogue, bridging the gap between science and art.
Some of the specimens featured in “Gems” are published for the first time.
The book was created under the scientific supervision of François Farges, a professor of mineralogy at the Muséum national d’Histoire naturelle, honorary professor at Stanford University, and member of the Institut Universitaire de France, specialized in environmental and heritage mineralogy.
Priced at $45, “Gems” is out in September.
The exhibition begins Sept. 16 and runs through May 4, 2021.
