On Monday evening, Tiffany & Co. unveiled the summer expression of its Blue Book 2026: Hidden Garden collection, which is designed to capture nature in full bloom. The unveiling marks the latest chapter for the “Hidden Garden” collection, and follows the spring introduction that debuted in April with reinterpretations and colorful twists of Jean Schlumberger’s iconic designs.

With new introductions of Paradise Bird, Daisy, Raffia, Blossom, and Petals, the intricate stories behind each piece come to life through sculptural movement and vivid colors.

“With the summer expression of Blue Book 2026: Hidden Garden, birds parade in a burst of color; their nests, woven from yellow gold, diamonds, and platinum, play with graphic contrasts,” says Nathalie Verdeille, Senior Vice President—Chief Artistic Officer, Jewelry and High Jewelry, Tiffany & Co. “They dialogue with
another art of weaving, that of raffia, whose strands inspire supple, geometric, and luminous structures. This collection celebrates the richness of colored stones—precious flowers set against interlacing patterns of gold and platinum. The tropics bloom in the colorful volumes of the Blossom chapter. It is a triptych of the tropics where shapes, textures, and shades compete in their flamboyance.”

For Raffia, textures of nature are reimagined with Tiffany & Co.’s legacy gemstone, the Sugarloaf tanzanite, punctuated by vivid rubies and diamond accents. Paradise Bird again reimagines the iconic Bird on a Rock, with each iteration perched on an exceptional gemstone, including American chrysocolla, Namibian purple calcedony, Nigerian spessartine, and more. The feathers are an arrangement of gemstones that echo the center stone with bursts of unexpected combinations throughout.

Blossom is meant to mirror a lush bloom, with exceptional cushion cabochon and oval rubellites taking the place of nature’s beauty. With Daisy, emerald-cut blue zircons are set against rich emerald cabochons, with each petal handcrafted in a fluid mesh composition illuminated by diamonds. Petals, which is inspired by Schlumberger’s ribbons, features cushion-cut periodts, hidden bud-like accents, and more.

The third and final chapter, fall, will debut later this year.
