The Hazen Diamond Necklace was designed by Harry Winston, Inc. This statement necklace comprises 325 diamonds with a total weight of approximately 131.43 carats in a platinum setting. The necklace has two sections: the upper section is a single row of emerald cut diamonds, and the lower section consists of 3-rows - a row of baguette cut diamonds and a row of round brilliant cut diamonds from which a “fringe” of pear-shaped diamonds are suspended. The necklace is versatile and can be worn as a classic single-row diamond necklace or an elaborate 4-row dramatic necklace. Mrs. Lita Annenberg Hazen donated the necklace to the Smithsonian Institution National Museum of Natural History in 1979.
