Blue Book 2025: Sea of Wonder
Seahorse
Adorned with an unexpected mix of coloured gemstones, the Seahorse designs are a bold celebration of texture and contrast. This breathtaking necklace in platinum and 18k yellow gold showcases unenhanced purple sapphires of over 11 total carats, blue sapphires, moonstones and diamonds.
The Seahorse chapter of Blue Book 2025: Sea of Wonder draws inspiration from Jean Schlumberger’s famed 1968 seahorse brooches, infusing them with a contemporary sensibility. The new designs—such as this brooch set with over 9 carats of unenhanced purple sapphires, a blue sapphire, moonstones and diamonds—reimagine the original motif with a more abstract, modern interpretation.
Artisans crafted the Seahorse necklace over a span of approximately 1,185 hours, setting the 18k yellow gold and platinum design with 22 round cabochon sapphires of over 11 total carats, 27 round cabochon moonstones of over 6 total carats, 60 oval cabochon moonstones of over 50 total carats and 980 round brilliant diamonds of over 68 total carats.
“This collection is a voyage into the depths of the seas, born from a series of diverse explorations. It is a journey into the depths of the House’s rich archives through the lens of my imagination and creativity, where we delved into Jean Schlumberger’s repertoire of Tiffany & Co. masterpieces to uncover even deeper layers of meaning and artistry.”
