Sotheby’s Auction Reveals Rare Treasures and Incredible Prices

Collectors, gem experts and jewellery lovers were buzzing with excitement in Geneva on May 15 when a whole host of incredible pieces hit the auction block. The three most prominent pieces – the Farnese Blue diamond and two 50 carat diamonds – soared far above their estimates to secure eye-watering prices.

The Farnese Blue diamond – a historic treasure passed down for 300 years in the same family – sold for an impressive CHF 6.7 million (£4.97m), far above its estimate of CHF 3.5 to 5 million. The 6.16 carat pear-shaped blue diamond was given to Elisabeth Farnese, Queen of Spain, as a wedding present in 1715 and was subsequently passed down through four of the most important royal families in Europe.

A further two lots got bidders in a frenzy – a 51.71 carat round diamond and a 50.39 carat oval diamond. Both sold above their estimates at CHF 9.26 million (£6.86m) and CHF 8.13 million (£6.03m) respectively. Discovered in Botswana, both diamonds are Type IIa D-colour with flawless clarity.

Individuals from more than 50 countries participated in the ‘Magnificent Jewels and Noble Jewels’ sale, which secured CHF 85.7 million (£63.5m) overall.

Other highlights from the sale include a 2.63 carat fancy vivid purplish pink diamond, which set an auction price record for a fancy vivid purplish pink. This particular diamond has a modified round brilliant-cut shape, which allows the colour and life of the stone to be shown to its full potential.

Other record-breakers included a pink sapphire and diamond pendant, set with an oval pink sapphire of 95.45 carats. It was bought for CHF 2.29 million (£1.7m) and far exceeded its lowest estimate for CHF 580,000! The previous record for a pink sapphire was secured at Christie’s in Geneva in May 2014.

Sotheby’s was certainly on a roll on May 15, with a further three diamonds setting world records. A highly unusual fancy vivid yellowish green diamond weighing 2.52 carats was purchased for an incredible CHF 939,000 (£696,613.65), and a 9.70 carat fancy light purplish pink diamond and a fancy purple-pink diamond of 5.04 carats also excelled.

Elsewhere, Kashmir sapphires proved their perennial popularity with excellent sales results. An opulent 1930s ring adorned with a 4.01 carat gem with a highly coveted ‘royal blue’ colour realised an above-estimate price of CHF 1.8 million (£1.3m), as did a step-cut blue sapphire of 11.64 carats.

A personal favourite of the Gem-A team – a 19th century emerald cameo and diamond bracelet – sold for four times its estimate at CHF 250,000 (£185,466). Jewels by Cartier and Van Cleef & Arpels performed strongly, as did signed pieces featuring animals and birds. Incredibly, a Van Cleef & Arpels ‘Zip’ necklace, created in the 1950s, sold for ten times its estimate at CHF 507,000 (£376,126).
