New York: Tiffany & Co. has unveiled Hidden Garden, the autumn chapter of its Blue Book 2026 high jewellery collection, completing a three-part series introduced across the spring, summer and autumn seasons.
Created under Nathalie Verdeille, Chief Artistic Officer, Tiffany & Co., alongside the Tiffany Design Studio, Hidden Garden explores botanical forms, climbing vines, flowers and wildlife through rare gemstones and intricate craftsmanship. The collection also revisits the house’s archives, drawing particularly on the fluid and imaginative design language of Jean Schlumberger.
Tiffany’s Blue Book tradition dates to 1845, when founder Charles Lewis Tiffany introduced the house’s celebrated catalogue. Over time, Blue Book evolved into Tiffany’s showcase for its most exceptional gemstones, craftsmanship and high jewellery design.
Across Hidden Garden, individual suites interpret nature through distinct combinations of colour and form. The Dahlia designs bring together 18K yellow gold, platinum and vivid green tsavorites, while Hanging Fruit references Schlumberger’s 1962 Two Fruit clip through a combination of spessartines and turquoise cabochons.
The Pineapple suite pairs unenhanced Sri Lankan sapphires with deep blue paillonné enamel, while Jasmine appears in two interpretations: one centred on white diamonds and platinum, and another combining platinum and yellow gold with pink kunzites.
Colour continues through the Palm suite, where unenhanced Mozambican rubies and diamonds evoke the movement of palm leaves. Twin Bud combines diamond-set platinum forms with Zambian emeralds, while Nest places Fancy Yellow diamonds within sculptural gold and platinum structures. Hand-engraved diamond-set forms further extend the botanical vocabulary through the Vine designs.
The collection also turns to the animal world. Monarch and Butterfly creations use combinations of padparadscha sapphires, white diamonds and Fancy Vivid Yellow diamonds to interpret the colour and movement of wings.
Among the most striking pieces are two Paradise Bird brooches, one incorporating a 37-carat rose quartz and another centred on a 31-carat cabochon chalcedony.
Tiffany’s celebrated Bird on a Rock motif also returns in a statement necklace featuring diamond birds positioned around a 22-carat Brazilian Santa Maria aquamarine, bringing one of the house’s most recognisable archival signatures into the latest Blue Book chapter.
With Hidden Garden, Tiffany & Co. closes Blue Book 2026 by bringing together archival references, exceptional coloured gemstones and highly technical craftsmanship, using nature not simply as ornamentation but as the organising language of the collection.
