This month, the famous 55 ct. Kimberley Diamond will go on display at the American Museum of Natural History in New York City. This is the stone’s first public appearance.


According to a museum spokeswoman, the stone will be on display in the Morgan Memorial Hall of Gems through at least June 2014 and is on loan from the Bruce F. Stuart Trust.


Described by the exhibit’s curator as “virtually flawless,” the stone is a 55.08-ct. champagne-colored gem. The diamond bears historical importance because it was discovered in the 19th century at the Kimberley Mine in South Africa (also known as “the Big Hole”), one of the first diamond mines of the modern era.


Originally discovered as a 490 ct. crystal, the Kimberley diamond was cut into a 70 ct. gem in 1921.  According to the museum, the stone was given its present emerald cut in 1958 to improve its brilliancy.
