BLUE BOOK 2026:
Hidden Garden
On July 7, 2023, Tiffany & Co. made a declaration that had never been made in the House's 186-year history: they named a gemstone after its source. The Tiffany Muzo Emerald. Not a Tiffany emerald — a Muzo emerald, bearing our name, set in Tiffany blue.
Extracted from the historic Puerto Arturo shaft in December 2019, the stone spent three years being cut, examined, and graded — before being placed in the hands of the world's authority on rare gems..
“This remarkable stone, weighing over 10 carats, is a continuation of Tiffany's longstanding heritage of acquiring the most coveted gemstones that Mother Nature has to offer.” Victoria Reynolds — Chief Gemologist & VP High Jewelry, Tiffany & Co.
You Step Through A Curtain
The Hidden Garden room at Tiffany Blue Book 2026 was designed to tell a single story — the story of a stone. And at the center of that room, elevated on its stand under a single beam of light, is a Muzo emerald.
“This collection—one of Tiffany & Co.’s most important traditions for over a century—honors the legacy of Jean Schlumberger while demonstrating how we continue to evolve it for today’s high jewelry client. Under Nathalie Verdeille’s creative leadership, and in close collaboration with our gemologists and artisans, we are pushing the boundaries of design and technical excellence.” Anthony Ledru — CEO, Tiffany & Co.
Hidden Garden Collection
The Blue Book is Tiffany's most prestigious annual collection — and 2026's Hidden Garden marks the highest-profile placement of a Muzo stone in the collection's history. 122 pieces. Three cities. One centerpiece.
Since the LVMH acquisition, high jewelry sales at Tiffany have quadrupled. The Blue Book 2026 represents that ambition at full force — and Muzo stands at its center.
“Collections like this don't happen on their own — it's a collaboration between gemologists, the design team and the artisans.” Victoria Reynolds — Chief Gemologist & VP High Jewelry, Tiffany & Co.
