This ring is the first in a series of upcoming geometry-inspired sterling jewelry. I heated 16 gauge wire to be able to bend it just right, then heated the ends until they melted into that signature artisan ball end. This ring's circle is approximately 16mm around, and the one pictured is a size 6 (US). I can make these in any ring size, as I will be making yours to order (the one pictured has sold). Please leave your ring size in the "messages to seller" section at the time of purchase.
