Beautiful. vintage Swiss coin is set in a brass bezel with sterling silver backplate and adjustable ring band. The bezel around the coin is brass and the hand twisted wire is also brass. A silver bezel would blend into the color of the coin but the mixed metals provide some contrast which helps the coin stand out. The ring band is currently set for size 8 but can easily be adjusted between size 7-9. IThe band is made of sterling silver that has been etched with a design and a patina has been applied to darken the recesses and highlight the the etched design. The ring band is about 1/2" wide and the edges have been filed and smoothed so it is very comfortable to wear. Do you have an old coin hanging around that you'd like to wear?
