Swiss native Ursula Muller began her career as a jewelry designer in 1985. Her signature clean, architectural style blends geometric shapes with softer materials; In the artist's words: "My molds originate from the geometrical repertoire [...] Most of my colliers and necklaces are flexible; they can be worn in different ways, depending on the clothes, the occasions or the mood" This distinctive blend of bold design and everyday wear has made Muller a Pistachios favorite.
