Something exceptional = Hermès Fusion

Leave it to Hermès to totally reinvent the idea of the chain for high-jewelry. The Enchaînements Libres collection gives a big and bold new spin to an old jewelry staple while still representing the codes of the Maison as a harness-maker and saddler—as well as a nod to its ties to the nautical world. While the collection debuted last summer, the pieces were brought to New York for the first time to be shown to clients. To present the stunning collection, Pierre Hardy, Hermès’ creative director of high-jewelry, took to the stage during a presentation at Jazz at Lincoln Center, where modern dancers, choreographed by Christian Rizzo, opened a show that looked more like a ready-to-wear runway than a high-jewelry presentation. A series of models clad only in black appeared afterward in the new jewels, allowing guests to get up-close to the pieces at the end of the presentation. ~ Robb Report
