Anodized Aluminum Jump Rings do not tarnish. The finish lasts a long time and will stand up to quite a bit of wear. Aluminum is a very light weight but strong metal.
***All jump rings come in dye lots. Order everything that you need for a project at one time as we can not guarantee that the color will be exactly the same if you order more later.
