We had to take this biker ring offline for awhile due to a shortage of good quality amber. That problem's been solved and I'm happy to say it's in production again. Crafted from .925 sterling silver, with a large amber stone (13mm by 18mm) in the middle, a size 10 weighs in at 21.3 grams. Expressive filigree work and no nonsense design will help you get in touch with your "inner biker"... or your money back!
