Tiffany & Co. Unveils Summer Debut of Blue Book 2025

Tiffany & Co. has introduced the summer edition of its Blue Book 2025 high jewellery collection, Sea of Wonder, designed by Nathalie Verdeille, the House’s Chief Artistic Officer of Jewellery and High Jewellery. Continuing its exploration of oceanic inspiration, the latest reveal brings new chapters centred on the seahorse and sea turtle, building on the legacy of Jean Schlumberger through a more conceptual and abstract lens.

The Seahorse chapter revisits a motif from The Tiffany Archives, taking cues from Schlumberger’s 1968 brooches. The reinterpretation brings forward expressive detailing and texture through bold combinations of coloured gemstones including unenhanced purple sapphires, moonstones and blue sapphires. One standout necklace in the collection, crafted over 1,600 hours, includes more than 11 carats of purple sapphires and is transformable into three different wear styles—either with or without its moonstone strand or worn as a standalone piece.

In the Sea Turtle chapter, Tiffany & Co. references archival brooches first introduced in Blue Book 1961. The reinterpretation emphasises the natural movement and sculptural form of the sea turtle, using aquamarines, turquoise and diamonds to mirror the tones and textures of the ocean. The result is a series of modern brooches that blend figurative artistry with technical precision.

Blue Book 2025: Sea of Wonder continues Tiffany & Co.’s tradition of high jewellery rooted in historical craftsmanship while evolving its aesthetic direction toward abstract storytelling and contemporary design.
