Christie is on sale for sale in Geneva next week, a very rare pink diamond weighs around 19 tickets and is expected to reach up to $ 50 million.
According to Christie's auction house, rectangular diamond is the largest pink diamond ever auctioned.
The diamond, entitled "Pink Legacy", belongs to the Oppenheimer family, which long dominated De Beers, who until the late 1950s was in the diamond industry.
Despite an estimated price between $ 30 million and $ 50 million, Christie's expects to attract private buyers from Asia. One of the characteristics of this strong pink diamond is that it is rectangular, usually used with white diamonds, making it unique.
In the last few years, colored diamonds have become very popular because the prices of precious stones in blue and pink are breaking the record in auctions.
