For over a century, Tiffany & Co.’s Blue Book has stood as the house’s most imaginative showcase — a stage for one-of-a-kind creations at the pinnacle of its craftsmanship. Blue Book 2025: Sea of Wonder carries that legacy forward, inviting collectors to see the ocean’s beauty through a dreamlike lens. Designed by Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry, the fall expression reinterprets Jean Schlumberger’s iconic marine motifs. Finally, Ocean Flora closes the story with a one-of-a-kind timepiece featuring a mother-of-pearl dial, turquoise hour marker, and diamond bracelet. Tiffany’s voyage through Sea of Wonder continues September 18 in Milan, where the house will debut the fall expression at an intimate, jewel-studded gala.
