Blue Book 2026

Hidden Garden

Showcasing the world’s finest diamonds and extraordinary colored gemstones, Blue Book 2026: Hidden Garden reveals a secret landscape where nature’s quiet transformations unfold in radiant beauty. Designed by Nathalie Verdeille—Senior Vice President and Chief Artistic Officer—alongside the Tiffany Design Studio, the newest high jewelry collection reinterprets Jean Schlumberger’s artistry and iconic flora and fauna motifs into sculptural masterpieces of exceptional beauty.













Monarch

Drawn from an archival Jean Schlumberger necklace, where a hidden Monarch butterfly gently rests amid twisting vines and sculpted foliage, the House reimagines these organic forms through a modern lens, uniting heritage and contemporary design.




Exquisitely Crafted

Blue Book 2026: Hidden Garden is an invitation into an enchanted landscape where blossoms, creatures and unexpected forms converge, brought to life through extraordinary craft.
