This one-of-a-kind ring is around a size 6 (US) but has the ability to adjust to become bigger. The metal smithing is hand-worked by me and I purchased the carnelian cab from Rio Grande. I created the crescent moon by hand-sawing the shape out of a 10 gauge sheet I rolled out using melted down sterling that I recycled from my other projects. Comes with a free polishing cloth. Made with love in Arizona, USA.
