The Captured Bead Bracelet, made using beautiful cold hard stainless steel rings and stainless steel ball bearings. Along with bronze, steel is one of the hardest metals I work with. The price is therefore slightly higher than the same thing in aluminum, brass, or copper. But the bracelet is more durable as well. Stainless steel won't rust nor darken with age, keeping its bright, clean look for years to come. This bracelet is held closed with a simple silver-colored lobster clasp.
