Earlier in July, in a side room at the De Beers offices in Paris’ on Rue de la Paix, a stone sat in a position of honor on a pedestal. This wasn’t just any stone: It was a 296-carat rough yellow diamond, approximately the size of a golf ball, its hue evenly balancing tone and translucence—a must for a fancy colored diamond. It dwarfed the other large diamonds nearby, which varied in size from 58 and 117 carats. Judging from the smile on the face of De Beers CEO François Delage, the yellow stone was his top prize. “It will be cut into a briolette,” he explained, adding that the finished teardrop-shaped gem easily would still top 200 carats.

The annual “high jewelry” presentations at Paris Haute Couture Week, which this year took place July 2 to 6 in Paris—coinciding with the Fall/Winter haute couture shows from Chanel, Dior and other high-end labels—often include such wow moments. This is when jewelry houses showcase the pinnacle of their craftsmanship and ability to source special stones with one-of-a-kind jewelry designs. Although many of these pieces are privately sold even before they are presented to the press, they create demand for the brand, in addition to lending some bragging rights.


Van Cleef & Arpels, for example, presented its Le Secret collection, with each piece more of a design marvel than the one that preceded it. Convertible jewels—such as necklaces that can be worn a variety of ways or that can be split into a necklace and bracelet, or a pendant that becomes a brooch—were key to Van Cleef’s high-jewelry work.

These presentations also reveal the convergence between the worlds of fashion and jewelry. Take Chopard’s Silk Road collection, which was inspired by a 2015 meeting between copresident and creative director Caroline Scheufele and Chinese fashion designer Guo Pei. Scheufele’s brilliant, often lace-like jewels strikingly complemented Guo Pei’s fanciful dresses and gowns in the latter’s runway show in Paris.

An interesting theme this year explores the interplay between light and color. Piaget’s Sunlight Journey collection, with its bold colors and mosaic-like designs, touched on this idea, says Jean-Bernard Forot, jewelry marketing director for the house. He cites the Amalfi Coast as the line’s inspiration. “When you wake up in the morning, you see how the early morning sun plays with the water,” Forot explains. “At midday, the sun is high in the sky, and the colors are much stronger. And in the evening, at sunset, those colors take on yet another feeling. It’s always the same place, and yet the light changes those moments, and perhaps your emotions.”


These high-jewelry collections can take anywhere from 18 months to two years to make, though some may require even more time. Taipei-based jewelry designer Cindy Chao, who favors nature-driven designs, spent six years thinking about how to craft the perfect dragonfly brooch. “My pieces are very organic, and I’m influenced by my father, who was a sculptor, so the pieces have a sculptural feeling,” she says. “The piece also has to present an artistic sense from 360 degrees, not just from the front. That’s the spirit and the essence of handcraft.”

Forot agrees. “Jewelry is serious when you work with precious stones and artisanship, but it’s also something you should enjoy,” he says. “You’re buying savoir-faire—and style.”
