Bonhams will hold its Fine Jewellery sale in Paris on 29 October 2026, bringing together more than 180 lots that span vivid coloured gemstones, signed jewels from the great French maisons and a dedicated section of artist jewellery. The sale positions Paris as a key autumn stop for jewel collectors ahead of the Geneva season. The lead lot is a pendant necklace by Kat Florence set with a cushion-cut neon-blue Paraíba tourmaline weighing 81.17 carats, carried on an openwork mount set with brilliant-cut diamonds. The stone, prized for its electric colour, is offered with an estimate of €60,000 to €80,000. Paraíba tourmaline remains one of the most sought-after coloured stones on the market, and examples of this size appear infrequently at auction. Further highlights include a Chaumet ring centred on a step-cut 13.70-carat Sri Lankan sapphire within a surround of eight step-cut diamonds (estimate €45,000–65,000), and a Cartier ring bearing an oval-cut 11.50-carat Madagascar sapphire between two pear-cut diamonds (€40,000–60,000). Two natural, unheated sapphires each weighing over 10 carats, from Cartier and Chaumet, anchor the coloured-stone offering, alongside creations by Buccellati, Lacloche, Zolotas and Lalaounis. The sale also features artist jewellery exploring the dialogue between jewellery and art, plus signed jewels of notable provenance from the collection of the milliner Madame Paulette, including designs by Schlumberger and Boucheron. Bonhams jewellery specialist Mathilde Rispe said the auction presents an exceptional selection distinguished by vibrant gemstones and rarity, aimed at collectors of fine jewellery. The Paris sale lands just ahead of the Geneva jewellery season, when Sotheby's, Christie's and Phillips all stage their flagship November auctions, and offers collectors an earlier chance to secure top-tier coloured stones and signed pieces before the Swiss sales rooms take over the calendar.
