Boucheron Hosted a Grand Hollywood Hills House Party to Celebrate its West Coast Arrival

“I feel sexy and like a boss!” Tracee Ellis Ross exclaimed to Vogue—understandably, given that she was dripping in at least 10-carats of Boucheron diamonds. The actress was among those taking the French jeweler's creations out for a night on the town on Wednesday evening. To celebrate the new-ish West Coast flagship, it was time for a lavish dinner party.

The storied maison unveiled its 5,296-square-foot boutique on Rodeo Drive during the summer, fusing its Parisian heritage with Hollywood glamour. As such, a mega-watt guestlist—and backdrop—worthy of Tinsel Town was called for to commemorate the milestone. Ross was joined by the likes of Julianne Moore, Laura Dern, and Natasha Lyonne for an elegant fete hosted in the majestic Harvey House. Nestled in the Hollywood Hills, the John Lautner-designed mid-century modern marvel has a worthy place on the National Register of Historic Places.

Inside, the exuberant, geometric house had been given a Boucheron zhuzh for one night only. Portraits of founder Frédéric Boucheron and his clientele from the Golden Age of film were on display, as well as pieces from the house's private collectsion. A gold, emerald, diamond, aquamarine, and opal butterfly brooch from 1900 that Elizabeth Taylor wore to the Oscars in 1976—a gift from Richard Burton—was prompting audible gasps in the room. Also given the museum treatment were the brand’s famed question mark necklace, while mannequins exhibited extravagant diamond, pearl, and gold necklaces. Some of the bedrooms inside Harvey House even had models lounging around, showing off the jewelry. Among the first guests to arrive, actress Judith Light was taking her time to peruse—perhaps planning a request for a future red carpet moment.

Soon, the party was flooded and attendees flexed their jewelry: Dern showed up in a stunning necklace and sophisticated chandelier earrings to match, while Ross paired her show-stopping Boucheron Torque necklace paved with diamonds, rock crystal, and onyx on white gold with sparkling rings and earrings. “This necklace kills me because it’s so beautiful,” she said. “Even the way the clasp is done, I love it and it feels like a little nod to both the future and history.”

Many of the gentlemen also brought high-octane glamour. Cooper Koch, the breakout star of Monsters: The Lyle and Erik Menendez Story, wore an exquisite Boucheron Quatre Black Edition bracelet and ring, both covered with diamonds and set in 18-carat white gold. Sprucing up his jacket’s lapel was the Flèche arrow brooch, made with 177 round-cut diamonds. “It’s fun to wear jewelry and be bling-bling, baby,” Koch laughed during cocktails. “I love being sparkly and glamorous. I’m happy that guys are wearing jewelry and embracing it.” Ross was inclined to agree. “I love that jewelry offers a sense of individuality. Seeing all the lovely women and men here tonight showing their sense of individuality, that’s so cool and beautiful.”

When the clock struck 8 p.m., some 70 friends of the house were ushered out to the backyard, which boasts sweeping panoramic views of downtown Los Angeles. There, an al fresco dinner of under the stars awaited, with the likes of stylists Warren Alfie Baker and Thomas Christos Kikis and director Gia Coppola tucking into poached halibut and beef short rib at a long table decorated with thistle and moss.

CEO Hélène Poulit-Duquesne welcomed guests over a brief Champagne toast. “Boucheron stands for creativity, innovation and freedom—the freedom to wear your jewelry your way, and the freedom to express who you are. That’s why Los Angeles feels so right for us. It’s a city of people who create and stand for themselves.”

The evening concluded with a performance by Nile Rodgers, the prolific musician, songwriter, and producer behind hit songs by Madonna, Mick Jagger, and David Bowie, to name just a few. As he launched into his hit Le Freak, actress Charlotte Le Bon immediately hit the dance floor… C'est chic, indeed.
