Tiffany & Co. unveiled fall additions to its 2025 Blue Book “Sea of Wonder” high jewelry collection at Shanghai’s Zhangyuan under Chief Jewelry Officer Nathalie Verdeille. The pieces reinterpret marine-inspired designs from legendary designer Jean Schlumberger, featuring three series: the Anemone collection with three unheated rubies, the Shell series in platinum and gold with diamonds, and abstract Mermaid designs including a black opal necklace. The exhibition also celebrated the 60th anniversary of Schlumberger’s iconic Bird on a Rock brooch.
