The Golden Eye Diamond is a flawless 43.51-carat (8.702 g) Fancy Intense Yellow diamond, claimed by one of its past owners to be the world's largest of its cut and color. It is believed to come from the Kimberley area of South Africa. Tom Moses, a senior vice president with the Gemological Institute of America, agrees that it came from South Africa, but it has not been able to be determined the mine of origin.
