Sea of Wonder: Blue Book 2025 by Tiffany & Co.

Tiffany & Co. unveiled the Blue Book 2025 in New York, the Sea of Wonder, an extraordinary high jewellery collection that celebrates the allure, motion and mystery of the oceans.

The House latest Blue Book reimagines the hidden wonders of the ocean. This collection is a testament to Tiffany & Co.’s commitment to creativity, craftsmanship and a deep reverence for nature’s infinite mysteries.

Tiffany was founded in 1837 by Charles Lewis Tiffany and John B. Young, in Brooklyn, Connecticut and pretty early on (in 1845) the company introduced the ‘Blue Book’ as the Tiffany & Co. ‘catalogue’. It was the first mail-order catalog ever issued in the United States. The catalog was – and still is – named after Tiffany’s iconic robin’s egg blue colour. It included Tiffany’s jewellery and luxury goods, allowing clients to browse and purchase without visiting the New York store. Over time, the Blue Book became a platform for Tiffany to introduce some of its most groundbreaking designs, especially under the leadership of legendary designers like Jean Schlumberger, Elsa Peretti or Paloma Picasso.

Today, the Tiffany Blue Book is an annual high jewellery collection with theme each year and showcases one-of-a-kind pieces – this year it is dedicated to the boundless beauty of the oceans.

The collection begins with the lush world of oceanic plants, captured in delicate designs that call to mind an underwater garden. Notable pieces from the Ocean Flora chapter include a necklace with magnificent Zambian emeralds—celebrated for their rich, verdant hues—that seemingly float atop a garden of diamonds.

The Seahorse chapter, inspired by Jean Schlumberger’s iconic 1968 brooches, reinterprets these creatures yellow gold and platinum, with blue zircons, sapphires, moonstones and diamonds. The Sea Turtle designs feature diamond-rich patterns and intricate gold details. The geometry of the turtle shell is beautifully sublimated by Tiffany artisans, who meticulously engrave each piece. The Starfish chapter deconstructs and reinterprets the ‘star of the sea’ into high jewellery with rubies from Mozambique and diamonds accented by 18k yellow gold, rose-cut diamonds and pavé diamonds.

The Urchin chapter draws from the intricate forms of the sea urchin, amplified through Jean Schlumberger’s visionary approach. Paillonné enameling—a 19th-century technique that Jean Schlumberger is credited with revitalizing—adds a delicate, thorny texture to the designs while capturing the iridescent essence of the sea.

Lastly, the Wave chapter celebrates the dramatic movement of the ocean through powerful, sculptural designs. The breathtaking Wave necklace evokes the opulence of a crashing wave, featuring diamonds accented by vivid blue cuprian elbaite tourmalines of over 17 total carats. The piece is inspired by the voluminous forms and dynamic motion found in Schlumberger’s famous Leaves Necklace.
