Vintage Ring with Branches and Green Glass Stone, size 6, unmarked

Unmarked vintage/antique ring in a silver tone metal, shaped like branches. The branches hold a clear glass peridot green color stone. Age unknown, I've had it over 30 years, bought as vintage. It's made a little roughly.
The ring is in very good condition. Aged and tarnished, needs to be cleaned if you like your metals shiny.
