Sotheby\u2019s latest High Jewelry Live Sale in Geneva delivered a strong signal that the top end of the global jewellery market remains resilient, with the auction house reporting total sales exceeding $30 million.
\nThe May sale drew participation from collectors across more than 30 countries and achieved the highest bidder engagement Sotheby\u2019s Geneva jewellery sales have seen in over five years.
\nThe auction totalled approximately $30.1 million, with 93% of the lots sold and more than 60% of pieces achieving prices above their high estimates. Sotheby\u2019s said bidding was led by collectors from the United States, Hong Kong, the Middle East and Europe.
\nJessica Wyndham, Head of High Jewelry at Sotheby\u2019s Geneva, noted that the momentum seen in late 2025 and recent Hong Kong sales continued strongly into Geneva, particularly for coloured gemstones and signed vintage jewellery. At the same time, the sale also highlighted a renewed demand for exceptional white diamonds.<\/p>\n

White Diamonds Make a Strong Comeback<\/strong><\/p>\n

\"\"<\/p>\n

One of the standout moments was the sale of a perfectly matched pair of unmounted De Beers white diamonds (pictured above), each weighing 18.38 carats. The Type IIa D-colour stones \u2014 one flawless and the other internally flawless \u2014 sold for an estimated $3.27 million, becoming the highest-value lot of the auction.
\nThe diamonds originated from Botswana\u2019s Jwaneng mine and formed part of a collaboration between Sotheby\u2019s and De Beers to showcase rare, provenance-backed diamonds as collectible works of art. Sotheby\u2019s had earlier sold \u201cThe Jwaneng 28.88\u201d diamond in Hong Kong for an estimated $2.7 million.
\nOther strong-performing white diamond pieces included:<\/p>\n

\"\"<\/p>\n

A 5.03-carat Graff diamond ring that realised an estimated $363,000 against a high estimate of around $160,000.<\/p>\n

\"\"<\/p>\n

An 8.99-carat step-cut diamond that sold for approximately $363,000.<\/p>\n

\"\"<\/p>\n

A 10.80-carat step-cut diamond ring that realised roughly $280,000.<\/p>\n

Rubies Dominated Collector Interest<\/strong>
\nRubies emerged as one of the evening\u2019s strongest-performing gemstone categories, with several pieces significantly outperforming estimates.
\nAmong the highlights:<\/p>\n

\"\"<\/p>\n

A cushion-shaped ruby weighing 3.19 carats set as a ring with a diamond surround sold for $230,793.<\/p>\n

\"\"<\/p>\n

A 6.49-carat unmounted ruby realised about $313,000.
\nThe auction house said intense bidding reflected sustained demand for untreated, vividly coloured rubies among global collectors.<\/p>\n

Exceptional Emeralds & Sapphires<\/strong>
\nEmeralds and sapphires also drew strong competition.
\nSome highlights included:<\/p>\n

\"\"<\/p>\n

A pair of step-cut sapphire and diamond pendant earrings weighing 35.74 and 30.54 carats respectively, and surmounted by brilliant-diamonds, sold for around $824,000.<\/p>\n

\"\"<\/p>\n

A Cartier sapphire and diamond ring realised approximately $264,000. It featured a 15.81-carat step-cut sapphire flanked by baguette, bullet- and fancy-shaped diamond shoulders.<\/p>\n

Vintage Signed Jewellery Surges<\/strong>
\nSigned jewellery from heritage maisons such as Bulgari, Cartier and Van Cleef & Arpels continued to attract aggressive bidding, particularly bold designs from the 1970s through the 1990s.
\nKey results included:<\/p>\n

\"\"<\/p>\n

A Bulgari Serpenti wristwatch from 1976 selling for an estimated $841,000.<\/p>\n

\"\"<\/p>\n

A Cartier sapphire and diamond demi-parure from the 1980s realising nearly $396,000.<\/p>\n

Overall, the Geneva sale reinforced two key market themes currently shaping the global high jewellery sector: sustained appetite for exceptional coloured gemstones and renewed confidence in top-quality white diamonds with traceable provenance.<\/p>\n","protected":false},"excerpt":{"rendered":"
