Delfina Delettrez has opened her first shop outside Italy, on London’s Mount Street. The designer has filled it with trompe l’oeil malachite, Giò Ponti lights and furniture, and small fur-filled alcoves to showcase some of the jewels.

“I wanted to enter into one of my pieces,” said Delettrez of her vision for the bijou space, the second store to open this week on Mount Street after Christopher Kane’s across the road.

The shop, at 109 Mount Street, spans 670 square feet over two floors, and was designed by Delettrez together with Rafael de Cárdenas from Architecture at Large.

The ground floor is her showcase and everyday business space, and has low petrol-colored velvet stools tucked under the display cases, a hanging Giò Ponti light that resembles a milky semi-precious stone, and antique chairs — small and spindly, with a black-and-white diamond pattern on the cushions — that she bought second-hand in Italy. Delettrez had the walls painted to resemble malachite, and installed little alcoves in the walls, which she filled with Mongolian lamb’s fur. A single jewel twinkles from inside all the shaggy fur.

It’s currently filled with design gems including a delicate Ponti wood and glass cabinet, two furry modernist chairs designed by Delettrez’s maternal grandmother Anna Fendi, and a swiveling coat stand and mirror by the Italian designer Joe Colombo.

The Mount Street opening is a milestone for Delettrez, who also happens to be in the process of moving from Rome to London for personal reasons.
