Maybe 4 or 5 oz of the 18g 5/32" rings from theringlord.com/cart/shopdispl…, and the pendant was around $8 from www.artbeads.com/6040-bls30.ht…. The problem is nickel silver rings are getting hard to find. I've made an identical copy to this one out of brass too. However, the nickel silver gives it that vintage look that I was going for.
As far as handcrafted, yes, I put the rings together one at a time using standard bent chain nose pliers, and patience.
