OPENINGS The lower level of a department store traditionally houses its least glamorous offerings. (At Bloomingdale’s on 59th Street in Manhattan, it’s how you get to the subway.) But at Saks Fifth Avenue’s New York City flagship, that’s where you’ll find Saks’ most precious gems: Appropriately named The Vault, the 12,000-square-foot space houses some two dozen jewelry and watch brands. On our visit, we spotted captivating pearl and colored stone styles from Assael; a stunning selection of Robert Procop pieces, including an almost palm-size aquamarine pendant; gorgeous red-carpet–ready designs from Martin Katz and Lorraine Schwartz; and enough Bulgari snakes to take over a plane. Plus, timepieces from the likes of IWC, TAG Heuer, and Vacheron Constantin ensure that male shoppers will be suitably entertained. (Above) Earrings with 12.11 mm South Sea pearls, 58.86 cts. t.w.
