PARIS — Sunlight turning pear-shaped orange diamonds into a spray of fire around the ear. A tiger’s striped coat turning into a graphic play of shadows, onyx and yellow gems against the skin. An emerald’s garden turns into a mesmerizing maze while curves turn a sapphire cabochon into a deep pool.

In the stark sunlight of the Mediterranean coast, every nuance and characteristic comes into view — and that’s exactly what Cartier is betting on for its latest high jewelry collection.

Revealed Wednesday in a Provençal castle just outside Saint-Tropez, “Le Chœur des Pierres” takes the four classical precious stones as its starting point and builds a full narrative around what the brand expects will leave no one stone-hearted.

“Letting a stone speak is to recognize in it a memory of the world, a beauty shaped by time and imbued with eternity,” said Jacqueline Karachi-Langane, director of high jewelry creation for the French jeweler. “Each gemstone is an encounter, an alchemy that resonates with our vision and our quest for the Cartier ideal.”

She added that a jeweler’s work was “to be moved, to interpret and magnify the stone’s unique soul, its presence,” creating a design that served to reveal “its nuances, brilliance, sparkle and inner vibration.”

Pierre Rainero, Cartier’s director of image, style and heritage, added that this collection’s focus on stones was particularly representative of the jeweler’s style, especially in “the association of colors, volumes [and] different cuts.”

“We also wanted to highlight that we work with different stones together,” he continued. “So that’s why there was an idea of chorus and heart,” playing on homophony between their French translations of “choeur” and “coeur” respectively.

There’s the green-blue pairing, something of a taboo when Cartier first used it in the early 1900s as “a very good idea to promote a different aspect of beauty,” Rainero said.

Other combinations nod to the aesthetics of China and India, such as red with green, or blue-red-green assortments used on the Tutti Kanya choral creation that ends on a 30.33-carat engraved Zambian emerald, he said. It also features a rubby tassel at the nape.

Nuances of the same color also came into play, such as different colors of diamonds from the same palette.

Case in point is the Haryma necklace, where yellow and orange diamonds come to play with garnets and white diamonds to create a shading effect on the necklace and figurative tiger descending a staircase arrangement supported by five imperial topazes, totaling just over 28 carats.

Best exemplifying the stones-first stance are Olorra, a wide necklace composed of radiating geometric pendants formed by custom-cut turquoise and lapis lazuli elements alternating with white diamonds, all set in white gold, and Panthère Kentia, where a 50-carat cabochon-cut Ceylon sapphire serves as the V-shaped design’s focal point — and resting spot for a panther figure with emerald eyes and onyx markings.

“What we can say about all these examples is how the stone is at the origin of a design,” Raniero said. “And not only origin of inspiration, but the design itself is conceived to drive the eyes toward the main stones.”

Chief marketing officer Arnaud Carrez told WWD that “the selection of stone is what differentiates Cartier; it is the defining principle. Beyond the quality, it is first and foremost the emotion that each and every stone will provoke.”

Take colored diamonds, which stood out across the 15 key pieces that were among the 130 novelties that also included objects and high jewelry timepieces unveiled in Saint-Tropez.

Having more than eight hues of the stone — plus garnets, lapis lazuli and onyx — is already a feat.  

But in the 1,900 carats’ worth of center stones — which include the oval gray diamond on the Keona ring, the brown-rose octagone-cut one on the Amberis ring and the set of six pink pears hailing from the now-shuttered Argyle mine in Australia — around a dozen exceed 20 carats, Carrez said.

That made for “quite a special collection” that feels different from previous years while remaining “very consistent” with Cartier’s identity, given the wealth of geometric motifs, Tutti Frutti styles and lightly figurative animal interpretations, the executive said.

He expects it to resonate with a broad high jewelry clientele looking for “excellence,” but also “consistency, coherence and audacity.”

If Cartier has continued to burnish its leadership position, it is “first and foremost due to the fact we have this capacity to embrace a large vision of the world,” he continued.

Putting stones with that je ne sais quoi front and center here tracks back to the jeweler’s focus on building emotional connections.

“Cartier has always been and will continue to be associated with personal milestones, with very important moments of one’s lives,” added Carrez, who said the “power and symbolic value of the [signature] red box, together with the creation, is even more important today.”

Hence also how Cartier distills its high jewelry chapters. Rather than a splashy gala, the Saint-Tropez event, timed slightly earlier than previous years and to be followed by a second chapter in Asia in the second semester and a third in February 2027, was intimate in scale.

This dovetails in what Carrez deemed “more of an evolution than a disruption” that also saw the house stage an after party following this year’s Met Gala or previous years’ teasing of new high jewelry opuses on friends of the house, like now-ambassador Zoe Saldaña.

Such events are “a fantastic lever to assert the maison’s positioning as a creative and cultural authority,” he said. They also create surprise. For Carrez, “the notion of unexpectedness in Cartier events has always been and will remain very important.”
