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. 

Almost all colors arrive in dye lots.  We have updated our photos to take some of the color variations into account but you should order everything you need at one time.
