Christie’s sells Bulgari Pink diamond for 12.1 million francs

Christie’s sold the 24-carat Bulgari Pink diamond ring for 12.1 million Swiss francs at its seasonal jewellery auction in Geneva, SRF reported. The emerald-cut pink diamond was the auction’s centrepiece.

The sale price was within the expected range of 10 million to 15 million francs. Coloured diamonds of this size are exceptionally rare. The ring had belonged to the same family since it was bought in the 1950s.

The diamond is thought to have come from the Golconda mines in southern India. Before the auction, Christie’s global head of jewellery, Max Fawcett, called it the “Mona Lisa of pink diamonds”.

The Golconda region produced some of history’s best-known and most valuable diamonds. Its mines supplied almost all the world’s known diamonds before large deposits were discovered in Brazil in the 18th century and later in Africa.
