The ocean has long been Tiffany & Co.’s muse, but in the Blue Book 2025: Sea of Wonder, the Maison renders its fascination with new brilliance. The Shell chapter, inspired by the sea’s infinite beauty, translates nature’s most whimsical forms into high jewelry of astonishing grace.

Here, the fluidity of the waves comes alive in undulating ribbons of 18k gold and platinum, each curve shimmering like sunlight as it dances across water. Diamonds sparkle with a liquid brilliance, echoing the ocean’s eternal movement, while each creation carries the quiet poetry of the tide.

At its heart lies a pièce de résistance: a brooch of hypnotic allure, set with a verdant green tourmaline of over eight carats, haloed by a constellation of diamonds. Like a treasure unearthed from the depths, it embodies Tiffany’s genius for transforming the raw power of nature into jewels of pure wonder.
