High-jewellery collections released by six houses steeped in history showcase distinct creative directions, with Bulgari’s chromatic fantasy, Cartier’s sculptural tension and Dior’s gem-packed dreamscapes leading the charge.

Bulgari unveils Polychroma, its most ambitious high-jewellery collection to date, featuring 250 exceptional creations, including 60 exclusive ‘millionaire pieces’ priced at a million euros or more. The collection dazzles with rare gemstones, each crafted into bold, exuberant forms. At its heart lies the Gallery of Wonders, a showcase of five masterpieces, including the Cosmic Vault necklace with a 123.35-carat sugarloaf sapphire, and the Celestial Mosaic necklace, centred around a 131.21-carat Tajikistan spinel. Polychroma’s vibrant palette and architectural silhouettes reflect the brand’s Roman roots while embracing a futuristic vision of opulence.

Cartier introduces En Équilibre, a poetic study in balance and tension, meticulously crafted over almost 100,000 hours. Highlights include the Shito necklace with vivid emeralds and the Hyala necklace featuring a 5.71-carat oval-cut diamond, both embodying sculptural elegance. The pieces explore kinetic harmony, where asymmetry and equilibrium coexist in a dance of light and form. Cartier’s signature craftsmanship is evident in intricate settings and fluid lines that evoke both strength and grace.

Dior’s Diorexquis draws from the fashion-forward legacy of its founder, blending magical galas and blooming florals into intricate seasonal designs. The collection features whimsical motifs – roses, ribbons and starbursts – rendered in pastel sapphires, spinels and diamonds. Each piece is a wearable tableau, echoing the couture house’s romanticism and theatrical flair.

The Bamboo capsule collection by Chaumet pays homage to nature’s grace, with 10 symbolic pieces inspired by the resilience and elegance of the grass family giant. A standout is the bib necklace showcasing a 13.19-carat black Australian opal, reflecting organic serenity. The collection’s minimalist aesthetic is elevated by the maison’s mastery of texture and movement, creating jewellery that feels alive and rooted in natural poetry.

Tiffany & Co.’s Blue Book 2025 embarks on a surreal seafaring voyage with Sea of Wonder, capturing oceanic hues and fluid forms that mimic marine life. The collection channels aquatic elegance, from the Seahorse blue zircon brooch inspired by Jean Schlumberger’s designs of the late 1960s to the charming Sea Turtle diamond pendant and the radiant Ocean Flora emerald necklace.

With Plume de Chanel, the maison of Mademoiselle reinforces its feathery signature. Chanel’s early plumes for hats and a 1932 jewellery collection featuring an articulated feather brooch set the scene for new high jewels that embody ethereal elegance. White diamonds shower light and empower grace upon statement rings, brooches, necklaces and earrings, with the motif extending to pink gold, sapphires and tourmalines.

Each maison tells a distinct story, fusing heritage, innovation and artistry into timeless expressions of luxury. These collections are not merely adornments but declarations of identity, imagination and craftsmanship. In a season where jewellery becomes narrative, the world’s leading houses continue to push boundaries, redefining what it means to wear art.
