I love working with brass. It is much harder than copper or silver, but turns out so nicely once it is formed.
This ring is 3/8" wide and was rolled through a rolling mill to get the pattern. It is riveted closed with 2 brass rivets. The ring fits a size 7.
All my rings are sealed with either paste wax or a spray sealer. This should help to not tarnish quickly. If it does tarnish, just polish with a good jewelry polishing cloth. A small anti-tarnish pad comes with the piece and should be kept with it. I always suggest removing rings before washing hands or working in any kind of liquids.
