Phillips has unveiled the headline lots for its Geneva Jewels Auction: VII, scheduled for 9 November, with two rings each carrying a top estimate of CHF 2.9 million, roughly $3.5 million. The first features a 1.35-carat fancy-vivid-blue diamond; the second centers on a 16.40-carat Kashmir sapphire set between diamonds. Other major jewels in the sale include a late-19th-century brooch-pendant built around an 18.69-carat Kashmir sapphire in a diamond surround, estimated up to CHF 1.2 million, about $1.5 million. A pair of Harry Winston earrings suspending 9.67- and 10.29-carat Colombian emeralds from diamonds is expected to fetch between CHF 600,000 and CHF 900,000. The November sale also marks the second edition of the Collections & Provenance section, a dedicated segment for period jewels, signed pieces and objects with exceptional histories. Among its highlights is a cultured pearl and diamond necklace from around 1928 that once belonged to Mary of Teck, the former Queen of the United Kingdom, with a top estimate of CHF 180,000, about $220,000. Geneva's autumn jewelry season is one of the principal anchors of the auction calendar for high-value gems, and the pairing of a vivid-blue diamond with a top Kashmir sapphire positions the sale at the luxury end of the market. Phillips is pitching the November edition as a showcase of rarity and provenance across both modern masterpieces and historic jewels. The Geneva sales rooms traditionally draw an international audience of collectors, dealers and private clients, and rare Kashmir sapphires in particular have commanded escalating prices as supply from the historic mines has effectively vanished.
