Bonhams is poised to host a distinguished jewelry auction in Paris on October 29, presenting an exceptional array of precious gemstones and historic pieces. The highlight of this highly anticipated event is a spectacular 81.17-carat Paraíba tourmaline necklace, a creation by Kat Florence, expected to fetch between €60,000 and €80,000 (approximately $67,000 to $90,000). This vibrant, neon-blue gem, meticulously cut into a cushion shape, is elegantly framed by brilliant-cut diamonds, embodying a fusion of natural beauty and intricate craftsmanship. The auction underscores a significant moment in the high-end jewelry market, offering collectors and enthusiasts a chance to acquire unique and valuable items.

The auction's allure extends beyond the magnificent Paraíba tourmaline, featuring a diverse selection of colored stones from various renowned houses. Among these, a Chaumet ring boasting a 12.5-carat Sri Lankan sapphire, verified as unheated, carries an estimate of €45,000 to €65,000 ($50,000 to $73,000). Similarly, a Cartier ring showcases an 11.5-carat sapphire from Madagascar, also confirmed to be free of treatment, with an estimated value of €40,000 to €60,000 ($45,000 to $67,000). Mathilde Rispe, Bonhams' French jewelry specialist, emphasized the sale's commitment to presenting 'an exceptional selection of jewels distinguished by vibrant gemstones,' highlighting the rarity and quality of the pieces on offer.

A notable segment of the collection originates from the personal effects of Madame Paulette, a celebrated milliner whose clientele included iconic figures like Greta Garbo and Princess Grace of Monaco. This includes a Cartier rose brooch from the 1940s, adorned with rubies, emeralds, and diamonds, estimated at €15,000 to €20,000 ($17,000 to $22,000). Other exquisite items from her collection are a charming Boucheron turtle brooch with an enamel shell, valued at €4,000 to €6,000 ($4,500 to $6,700), and a Schlumberger brooch depicting a dog's head crafted from coral, holding a lapis ball, with an estimate of €5,000 to €6,000 ($5,600 to $6,700).

The sale also features creations from other prestigious designers, such as a Mario Buccellati cuff intricately set with an emerald and rubies, anticipated to sell for €10,000 to €20,000 ($11,000 to $22,000). An elegant Lacloche Frères négligée necklace, dating back to approximately 1912, combines rubies and diamonds and is estimated between €6,000 and €10,000 ($6,700 to $11,000). Furthermore, a private collection contributes a range of Greek jewelry by Zolotas and Lalaounis, with expected prices in the €5,000 to €8,000 range ($5,600 to $9,000). The auction concludes with avant-garde artist jewelry, including two 1970s pieces attributed to Alberto Giorgi, a pivotal figure of the Fano School: a lacquer-and-diamond brooch (€4,500 to €6,500) and a malachite necklace (€2,800 to €3,800), offering a glimpse into mid-20th century artistic expression in jewelry.

The upcoming Bonhams auction in Paris is set to captivate discerning buyers with its unparalleled assortment of jewelry.
