I love this little series I made called Silver Moons. Each one is slightly different in texture and size, but all of them are the same shape.
This particular Argentium silver ring tapers from 1 1/8" down to 1/2" in the back and then back up to 3/4". The pattern was achieved by running the silver through a rolling mill. A patina was applied to accentuate those patterns.
The ring fits a size 8 to 8.5.
Argentium silver is very tarnish resistant. However I do send a small black anti-tarnish pad with the ring which should be kept with it when not being worn.
