Three world records were set in our Magnificent Jewels and Noble Jewels auction in Geneva, which totalled 91,778,750 CHF ($95.3 million), with over 90% of lots sold. The Graff Ruby, “a gem among gems”, reached CHF 8.3 million, achieving a world auction record for a ruby.

Another world auction record was achieved for a Kashmir sapphire, which sold for CHF 5.8 million. Jewels from the Mavrommatis Collection together realised CHF 26.6 million.
Queen Joséphine’s Natural Pearl Necklace soared above estimate to achieve CHF 3.3 million. A further record was established for a Cartier Mystery Clock “Model A” (CHF 845,00).
