To celebrate its one year anniversary, this morning Sotheby’s Diamonds revealed its most exceptional gem to date: a 102.34 carat, D Flawless, Type IIA round brilliant diamond, which the auction house describes as “the rarest and most valuable white diamond ever to come to market”.
The diamond was cut from a 425-carat rough mined by the De Beers group in Botswana. The cutting process took over six months and required the diamond to be transported between Johannesburg and New York.
