Unique Stainless Steel and Vibrant Blue Handmade Metal Chain Necklace This weave is named captive because there is one ring trapped inside of a cage, made by the rings surrounding it. The caught ring sits perpendicular to the cage rings. In this chain necklace we have used Blue colored aluminum as the trapped ring. This makes it look as though the blue is woven through the inside of the necklace. I get complements on it every time I ware it. It's a definite eye catcher! In the future we will be able to offer other color variations. 8.5 mm wide, finished with a Lobster Clasp.
