FOR ARTS SAKE: To fete her new collection and airy new office digs, jeweler Monique Péan presented her Seto line in tandem with an art installation. The designer, an avid art fan, invited guests to view “The Broken Kilometer,” a piece from 1979 by Walter De Maria. Presented by the Dia Art Foundation, the piece features five rows of spaced brass rods whose distance in between expands with each rod placement. The piece worked back to the jewelry, which featured rods on necklaces, earrings and rings. The minimalist mood was also inspired by a recent trip to Japan and the graphic aesthetic of architect Tadao Ando, which were evident in stones such as agate and quartz done in sculptural settings. One pair of earrings resembled a “Japanese Sunset,” according to the designer, while another stone had the look of a Japanese Bonsai plant. The jewelry was displayed in cases around a similar brass rod sculpture on the floor of her studio. The art will be on display at 393 West Broadway through June.
