It’s a breakthrough moment for Ralph Pucci and his eponymous gallery.

On June 23, Ralph Pucci International becomes the first American exhibitor of home furnishings design at the prestigious Château La Coste in Provence, France.

The exhibit, titled “Pure,” is a stand-alone show of works by leading artists and designers created entirely at Pucci’s New York studio and factory on 18th Street in Manhattan’s Chelsea neighborhood, using his proprietary “Plasterglass” material. “Plasterglass imparts the look of plaster and honors the artists’ original fingermarks yet is known for its durability,” Pucci explained.

While a wide range of colors are possible, the tables, lighting and seating featured in “Pure” have been realized entirely in white, and all the pieces have been crafted by hand with clean lines, variations on texture and no adornment. Pucci has continually pushed the boundaries of form and material. At this exhibit, plaster and clay will be hand-sculpted into the final design and then sold, all on site.

At the Château La Coste, inside the Oscar Niemeyer Pavilion, Pucci will be displaying pieces by 13 designers, among them Patrick Naggar, Eric Schmitt, John Koga, Paul Mathieu and Elizabeth Garouste. He said the exhibit will “highlight the timelessness of sculpture, reinterpreted through innovative contemporary design. I selected some of my iconic pieces, which in my opinion, are the ones we created and executed the best. They’re not necessarily the pieces that were most financially successful, but they’re the most exciting.”

Adding another special element to the exhibit, Pucci’s longtime master sculptor, Michael Evert, will conduct live sculpting sessions, offering an intimate glimpse into the workings of Pucci’s New York sculpture studio. In the background, the soundtrack will be jazz, which Pucci loves. You can always hear jazz piped inside to the Pucci gallery, and the playlist for Pucci’s Château La Coste show pays homage to the musical artistry of the ’50s (when the company was founded by Ralph’s parents, Nick and Lee) and such greats from the era as Chet Baker, Miles Davis, Lee Morgan, and the Modern Jazz Quartet. Pucci also created a book called “Process,” which is about the pieces in the exhibit and how they were made. He also had miniatures of the pieces made for the gift shop at the Château La Coste.

Château La Coste is a sprawling 600-acre cultural destination for art and architecture in Provence, France, situated between the historic city of Aix-en-Provence and the Luberon National Park. The setting has a history that dates as far back as the Roman Empire and the wine-making of the ancient time. The estate itself, with its main Palladian-style building, dates back to the late 1600s.

The Château La Coste’s current incarnation was created by billionaire developer and hotelier Patrick McKillen in 2002, who transformed the estate into a unique setting for art and a modern winery. There are scores of sculptures on the property, including pieces by Richard Serra and Louise Bourgoise, set in the open air, and contemporary art displayed in five galleries. There are also restaurants, a wine cellar and two hotels, as well as the vineyard, a chapel designed by Tadao Ando, and a music pavilion by Frank Gehry.

“Just wandering through and looking at everything, I feel it is one of the most inspiring places I have ever been,” said Pucci. “It’s a wonderful experience. You’re surrounded by nature amid the magical light of the south of France.”

Pucci’s exhibit commemorates the 70th anniversary of Ralph Pucci International, and 50 years since Ralph took the helm of his family business. Originally, it was a mannequin repair shop and later a manufacturer of mannequins. Over the years, Ralph evolved the business into showcasing luxury furniture and lighting, as well as sculpture, photography and art, as the demand for mannequins from retailers dried up. The furniture chapter began in 1989 when French interior designer Andrée Putman created a mannequin for Pucci and then urged Pucci to represent her furniture in the U.S.

Throughout the year, Pucci stages openings at his three galleries New York, Los Angeles and Miami. On those occasions, the settings become festive gatherings for artists, decorators, designers, clients, collectors, photographers and media.

It was a stroke of serendipity that led to Pucci to exhibiting at the Château La Coste. Seven years ago while in France to attend a show by French interior designer Paul Mathieu, Pucci was at the Marseille Provence Airport with his son Michael and ran into McKillen. The two were both on their way to the Château La Coste when they decided to share a cab. “We spent 35 minutes together,” Pucci recalled. “We began chatting and our mutual esteem for each other’s work quickly became apparent. I planted a seed about doing something with Pucci, and we kept in touch.”

Thus, the idea for a Ralph Pucci show was ignited. “I have always celebrated art in all its forms — whether that is in music, painting, photography, dance, sculpture, architecture — and this show is an exciting opportunity to bring that together. Château La Coste is so well respected on a global level as a leading arts destination and it’s exciting that Paddy [McKillen] has chosen to spotlight us and contemporary design in this inspiring environment. He’s really into design and the creative arts, so we totally hit it off.”
