Dorothee Rosen is a German-born, Canadian-based jewellery designer. (You can read more about her here.) These rings are called one-footers because, “A one foot length of sterling silver or 18k gold wire is first forged in various directions, much like life pushes and pulls us. The wire is then wound repeatedly into a continuous loop, wrapping around the finger many times without beginning or end. This design started as a drawing in brush and ink; the undulating line of the brushwork can still be detected in the translation into metal. Because each one is wrought by hand, the flow of wire finds its own way each time I create a new ring. Thus, every Onefooter ring is unique and different; no two are the same.”
This ring is sold at Facere Jewelry Art in Seattle. They are also available set with gems other than diamonds.
