The Hazen Diamond Necklace was designed by Harry Winston, Inc. The necklace is made of platinum and contains 325 diamonds that have a total weight of approximately 131.4 carats. A major factor leading to diamond's popularity as a gem was the development of cutting styles that best display the diamond's brilliance and fire. The Hazen Diamond Necklace is a good example of this as it incorporates several different cutting styles, including the pear, baguette, square, and round brilliant cuts. Mrs. Lita Annenberg Hazen donated the necklace to the Smithsonian in 1979.
