How much money is the worlds largest diamond worth?
With the given estimated value for the 530.20 carats (now owned by Queen Elizabeth II) alone that is over £200 million or $400 million. Let’s calculate (actually, just an estimate), the world’s largest diamond ever found is the Cullinan Diamond which is 3,106.75 carats (621.35 g or 1.3698 pounds). World’s largest diamond = 3,106.75 carats Queen Elizabeth II’s = 530.20 carats = over £200 million (estimate value) 3,106.75 carats divided by 530.20 carats = 5.86 X over £200 million, we will arrive to an estimate value of over £1.172B. That’s my own calculation only since there’s no published cost of the world’s largest diamond. And how much it was being sold before as a birthday gift to Britain’s King Edward VII, it is not known. http://www.history.com/this-day-in-history.do?action=VideoArticle&id=4711 January 25, 1905 World’s largest diamond found On January 25, 1905, at the Premier Mine
