American Golden Topaz
Record: The Largest-Cut Yellow Topaz In The World
The American Golden Topaz currently holds the record for the largest piece of cut yellow topaz in the world. More importantly, it is one of the largest faceted gems of any kind. It is sized at 22,892 carats (4.5785 kg) and has 172-facets (flat-faced cuts applied to gems, in order to help them reflect light.) The gem was cut from a piece of yellow topaz that was 11.8 kg (26 lb) in size. The original mineral was discovered in the Minas Gerais, Brazil, and cut by Leon Agee over a period of two years. In 1988, the American Golden Topaz was donated to the Smithsonian Institute, and put on display in the National Museum of Natural History in Washington, D.C. The price of the gem remains unclear.
