Harry Winston was an American jeweler known for donating the Hope Diamond and Portugese Diamond to the Smithsonian museum. As a child he grew up in his father's jewelry shop, and once recognized a two-carot emerald, which he bought for 25 cents and later sold for $800. He also redesigned the jewelry collection of Arabella Huntington into more contemporary styles.
