Diamond

Twenty carats of pear-shaped colorless diamonds accentuate the fancy brown (cognac) pear-cut diamonds in these earrings and brooch. Known as the Thompson diamonds, this set was made by Harry Winston in the 1950s and is on display at the Smithsonian National Museum of Natural History. The brown pear cut diamond in the brooch is quite a bit longer in shape than those in the earrings. Photo by Cliff. Licensed under CC By 2.0.
