Sea of Wonder: Celebrating the Ocean’s Endless Bounty with the Tiffany & Co. Blue Book 2025
Let's begin to explore this summer season's selection of exquisite high jewellery pieces with a collection that evokes dreams of gorgeous seaside resorts. The Tiffany & Co. new Blue Book chapter launched in 2025 is aptly called 'Sea of Wonder', taking us into a serene marine world that's perfectly infused with diamonds and coloured gemstones. Here are some of the creations that became an integral part of the Tiffany & Co. underwater world, including starfish, crashing waves and sea turtles…
Through the language of jewellery, the brand's Chief Artistic Officer, Nathalie Verdeille, is taking high jewellery lovers on a journey through the mysterious ocean depths, drawing her key inspirations from the archive works of the legendary designer Jean Schlumberger. Before we move to the review of the latest jewels, let's quickly delve into the past and discover the story of this extraordinary artist.
The French designer was born in Alsace, France, in 1907 into a family of textile manufacturers. The most obvious career choice for him would have been to continue in the family business. However, young Schlumberger was fascinated with drawing and became determined to forge his own artistic path. In his early twenties, he went to Paris, where he first worked for the French couturier Lucien Lelong and then for an art publisher. He dived into the vibrant, hedonistic, and rebellious art life of the city, which was full of new ideas and cultural influences.
Jean Michel Schlumberger (1907-1987)
There, Schlumberger started creating fashion jewellery using antique fragments, corals, shells, cameos, and porcelain flowers. They were extremely popular among members of the bohème. One day, a pair of his earrings worn by Princess Marina, Duchess of Kent, caught the eye of the famous couturier Elsa Schiaparelli, who subsequently commissioned Schlumberger to create fantasy buttons for her collections, the most notable of which was a flying acrobat concept for the 1938 Circus Collection. Having masterfully completed the commission, Schlumberger joined the list of acclaimed artists who worked for Schiaparelli, along with Salvador Dali, Jean Cocteau, and Louis Aragon. These surrealist jewellery pieces gave rise to the so-called “bijoux fantaisie” (fashion jewellery).

Through the collaboration with Schiaparelli, Schlumberger became known worldwide, especially in the United States, but his career was interrupted by the events of World War II and military service. It was not until 1946 that he opened a small boutique on East 63rd Street in New York City together with his childhood friend Nicolas Bongard. Schlumberger coined his own signature style, bringing movement, life, colour and emotion to jewellery. His pieces were infused with deep meaning based on historical and cultural references; he also brought back yellow gold and bright enamels. This approach made him incredibly popular among connoisseur clients from high society.

In 1956, the talented French jewellery designer Jean Schlumberger was invited to meet Walter Hoving, chairman of Tiffany & Co. He was offered access to a fascinating treasure trove of precious stones and complete freedom to create fantastic masterpieces. It was a milestone for both parties – Schlumberger became a designer for Tiffany & Co., and the company, in turn, started implementing an entirely new business model for the rapidly changing post-war world. It included combining the brand's heritage with the modernity, innovation and uniqueness of Schlumberger's creative vision.

In collaboration with Tiffany & Co., he presented his own perceptions of nature, including a less literal depiction of earthly wonders – fish, flowers, birds, plants and trees. He frequently travelled to Bali, India, Thailand and Guadeloupe, where he was drawing, sketching and painting, inspired by the world around him and passionate about the sea. Schlumberger created jewellery and objects in the form of sea urchins, starfish, sea anemones and shells that were whimsical yet realistic. "I'm trying to show things growing unevenly, chaotically, organically, constantly in motion," he is quoted as saying. "I want to capture the irregularity of the universe."

In his work for Tiffany & Co., the designer always paid special attention to sketching to reflect the smallest details produced by his imagination. Drawings created by Schlumberger in the previous century come to life in the 2025 Sea of Wonder collection and feel incredibly fresh in Nathalie's new jewellery interpretation.

The new collection and its 50 high jewellery pieces celebrate Schlumberger’s favourite sea creatures embodied in gold, platinum, diamonds and coloured gemstones. The collection is divided into several chapters, and I’d love to start with my favourite one – Seahorse, which features zircon as the main character. Unfortunately, this stone is often confused with cubic zirconia, which I talked about on Instagram. In this chapter, it stands out against the background of moonstones, diamonds and sapphires. The highlights of Seahorse are a bib necklace and a brooch inspired by Jean Schlumberger’s famous seahorse brooch from 1968. New designs, such as a necklace with over 80 carats of blue zircons, elevate the original motif of flowing gold ‘ribbons’ into something more abstract and contemporary.

The Starfish pieces are inspired by a diamond and pearl brooch created by Jean Schlumberger in 1956, during his first year at Tiffany & Co. Today’s interpretation beautifully reimagines the original piece in a variety of textured silhouettes, including platinum and 18k yellow gold earrings set with over 4 carats of untreated rubies, a ring with a similar 6-carat stone, and a necklace with a transformable pendant that can be worn as a brooch.

The rubies that we acquired for the Starfish chapter possess this gemstone’s most sought-after qualities: a strongly saturated red colour with a splash of fluorescence that is further enhanced by their high clarity. The unenhanced nature of these gemstones, coupled with the perfectly matched red colour and cut, is extremely rare. They are complemented by rose-cut and round brilliant diamonds that add a bit of antique inspiration with a modern twist. – Tiffany & Co’s Chief Gemmologist, Victoria Wirth Reynolds
The Urchin chapter draws inspiration from the intricately twisted gold ‘rope’ – a signature element of Schlumberger’s designs – and the sea urchin, first introduced as part of an iconic 1960s table clock. This chapter is an ode to yellow diamonds, as they adorn most of the jewels: the necklace features a central yellow diamond of over 18 carats, while the rings boast 12 and 9 carats. Three Urchin jewels are also decorated with paillonné enamel, a 19th-century technique revived by Jean Schlumberger, which adds contrast to the designs while simultaneously mimicking the iridescent essence of the sea.

The Wave chapter celebrates the dramatic movement of the ocean with voluminous diamond jewels featuring green and blue cuprian elbaite tourmalines. For example, the spectacular articulated necklace is set with diamonds to highlight the electric hues of over 17 carats of blue and green elbaite tourmalines. The piece is inspired by the voluminous shapes and dynamic movement first used in Schlumberger’s famous Leaves necklace in 1956. It is complemented by several earring and ring options featuring the same stones. For those who prefer a monochrome palette, there are several pieces with colourless diamonds. By the way, you’ve probably already seen Natalie Portman wearing the necklace on the red carpet at the Cannes Film Festival.

Of course, the collection introduces some new motifs. The ocean comes alive in the Ocean Flora chapter, blooming with fantastic sea plants. The necklace brings together five exclusively selected unenhanced Zambian emeralds totalling more than 10 carats. Elsewhere, the Sea Turtle chapter combines sophisticated diamond-studded patterns with intricate gold detailing. A standout design, the Sea Turtle pendant features a cushion-cut diamond weighing over 4 carats and has a hidden mechanism that transforms the piece into a brooch, reflecting the turtle’s journey from land to sea. Just imagine that it took over 900 hours to create!

The expertise of our craftspeople is especially evident in the Sea Turtle chapter, where the turtle’s geometric, graphic shell is adorned with hexagons, each formed by 24 delicately hand-engraved petals. Each piece demands more than 550 hours of meticulous craftsmanship, resulting in hypnotic volume and texture. – Nathalie Verdeille
