Torun grew up in Malmö with her sculptor mother, town planner father and three older siblings.

[4] In 1948 she traveled to Paris and Cannes, where she met painters Pablo Picasso, Georges Braque and Henri Matisse.

[2] She then remarried and moved to Paris with her third husband, the African-American painter Walter Coleman, with whom she later had two children, Ira and Marcia.

[3] In 1958 the family moved to Biot in the south of France to avoid the political problems they were encountering in Paris as a result of the war in Algeria.

In 1962, Torun designed a stainless steel bangle-style wristwatch for an exhibition at the Musée des Arts Décoratifs in Paris.

In 1992 she was awarded the Prince Eugen medal by King Carl XVI Gustaf of Sweden for outstanding artistic achievement.

Torun has been praised for her ability to shape solid materials into seemingly flexible forms, so that metal flows like water around the wearer's neck and shoulders.

[4] Her work can be seen in the Museum of Modern Art in New York City, the Swedish National Museum in Stockholm, the Musee des Arts Decoratifs in Montreal, the Louvre in Paris, the Worshipful Company of Goldsmiths in London, and in the Pinakothek der Moderne in Munich.
