Since its founding in 1906, Van Cleef & Arpels has always been a leader in luxury jewelry, adorning stars and royals with the world’s rarest stones while also innovating unique and now-patented techniques within the art form. A new exhibition nestled in the Hall of Gems and Minerals at the American Museum of Natural History—“Garden of Green”—explores the rich history of the brand through 44 archival pieces, all featuring green gemstones such as emerald, jade, jadeite, malachite, and peridot. Highlights include a beaded-emerald necklace, almost 800 carats, once owned by Doris Duke, and an Art Deco cabochon bracelet displayed in Paris at the 1925 World Fair. My personal favorite is the 2008 Rêverie clip, a peridot tree with a little diamond swing, reminiscent of the Rococo masterpiece by Jean-Honoré Fragonard, The Swing. —Lucy Horowitz
