GENEVA.- Today, Sotheby’s Geneva sale of Magnificent & Noble Jewels was led by the “Graff Ruby” from the Collection of Dimitri Mavrommatis. The 8.62 carat cushion-shaped gemstone soared above estimate and set a world auction record for a ruby at CHF 8,285,000 ($8,600,410), as well as a record price per carat for a ruby at $997,727* when it sold to Laurence Graff (lot 470, est. CHF 6.5 - 8.56 million / $6.8 - 9 million)*. This spectacular gemstone displayed the coveted “pigeon blood” red colour associated with the finest rubies from Mogok in Burma, arguably the rarest of all gemstones.

Another highlight of the evening was a natural pearl and diamond necklace formerly in the collection of Joséphine de Beauharnais, Queen of Sweden and Norway (1807-1876) and likely once the property of Joséphine de Beauharnais (1763-1814), first wife of Napoleon Bonaparte and Empress of the French. Comprising 111 pearls, the necklace achieved CHF 3,301,000 ($3,426,669) (lot 431, est. CHF 765,000-1,340,000 / $800,000-1,400,000). This result also demonstrates once again the extraordinary appeal of natural pearls which often sold for many multiples of their estimates today.

Today also saw exceptional prices for fine diamonds, coloured gemstones and jewels signed by the world’s greatest makers, which brought the sale’s total to an outstanding CHF 91,778,750 ($95,272,767), with 90.2% lots sold (est. CHF 59.2 - 90.2 million / $61.4 - 93.6 million).

Commenting on today’s results, David Bennett, Chairman of Sotheby’s Switzerland and of the Jewellery Department for Europe and the Middle East said: “The Graff Ruby mesmerizes all who view it. It is truly a gem among gems, and quite simply the greatest ruby of its size I have ever seen. The record price achieved tonight is also a tribute to the discerning eye of Dimitri Mavrommatis and his intense passion for beauty in all its forms”.

Shortly after the sale, Laurence Graff made the following statement: “It was a natural thing to do. Graff deals in the finest gemstones in the world and this is the finest ruby in the world. We are very proud to have it in our possession for the second time.”
