Tiffany & Co. celebrates the ocean’s splendor with the summer unveiling of Blue Book 2025: Sea of Wonder, a high jewelry collection led by Chief Artistic Officer Nathalie Verdeille. Debuted in Hong Kong on June 6, this latest chapter continues the House’s tradition of reimagining Jean Schlumberger’s archival designs through an aquatic lens.

The Seahorse chapter revives Schlumberger’s 1968 brooches, evolving them with unexpected gemstone pairings – unenhanced purple sapphires, moonstones, and blue sapphires. A standout necklace, requiring nearly 1,600 hours to create, dazzles with over 11 carats of purple sapphires and a transformable design that offers three ways to wear it.

Equally striking, the Sea Turtle chapter nods to the 1961 Blue Book with modern interpretations of the creature’s graceful form. Aquamarines, turquoise, and diamonds evoke the fluidity and light of the sea, culminating in sculptural, one-of-a-kind brooches.

With Sea of Wonder, Tiffany & Co. blends technical mastery with poetic storytelling, offering a mesmerizing tribute to the mysteries of the deep.
