A rare 6.16 carat blue diamond, known as Farnese Blue Diamond, has been sold at auction in Geneva at Sotheby for $6.7m (£5m). It sold after just four minutes of bidding starting from $3.5m.
The identity of the new owner has not been revealed. It was a very special jewelry piece, which has spent the past 300 years in Europe's royal houses passing through the generations. The diamond comes from the famous Golconda mine of India. The first historical record dates from 1714-15. In 1714, Philippe V (1683-1756), King of Spain married an Italian princess: Elisabeth Farnese, daughter of the Duke of Parma. It was given to Elisabeth Farnese, Queen of Spain, as a wedding present, at that time. „Apart from its beauty, the stone symbolises 300 years of history. It has traveled around Europe from Spain to France, Italy and Austria during these three centuries. And all this time, it was hidden away in a royal jewellery box. Except for close relatives, and of course the family jewellers, no one knew about its existence,” the description at Sotheby’s website said.
It appeared first time on the market Tuesday.Blue diamonds are colored by trace amounts of boron that contaminate the crystalline lattice structure. Color is considered the absolute most important criterion in grading a blue diamond and determining its value. Color is also divided into three components: hue, saturation, and tone. But in the case of Farnese Blue Diamond its special history was to be considered.
