In the world of fine jewellery, some collections are organised around a theme. Others are built around a sensation. With the new chapter of Blue Book 2026, Tiffany & Co. favours this second approach, allowing colour to guide the eye from one creation to the next.
And so, colour becomes the starting point. The deep blues of tanzanites, the luminous greens of peridots, the shades of pink in rubellites and the iridescent sheen of opals come together to form a composition in which each stone defines its own territory.
This approach has its roots in the work of Jean Schlumberger, whose creations often drew inspiration from the observation of living things. Rather than replicating his style, Nathalie Verdeille now carries on his spirit. Birds, flowers and plant fibres serve as a starting point for exploring volume, texture and rhythm.
The pins Paradise Bird illustrate this freedom. The birds are neither realistic nor purely decorative. They appear as fantastical figures, built around gemstones chosen for their unique character. Colours are layered, materials complement one another, and each composition seems suspended in a moment of movement.
This research is also reflected in Daisy, where the geometric precision of the petals contrasts with the fluidity of their execution. The eye moves from one detail to the next, discovering slightly different curves, as if each flower had its own personality.
With Raffia, the house focuses on the art of weaving. Gold and platinum threads intertwine around bluish tanzanites, creating graphic structures inspired by natural fibres. A reflection on the material that echoes the formal explorations once undertaken by Schlumberger.
Next come Blossom and Petals, two variations on the theme of blossoming flowers. The first emphasise density and volume; the second, lightness and fluidity. Underlying both is the same intention: to give the jewellery an organic, almost dynamic presence.
In this new chapter of Blue Book 2026, The house captures the energy, contrasts and transformative power of nature. An imaginary garden where every stone seems to have found its season.
