Sterling Silver scrolled ring with deep purple stone, Size 8

This ring was purchased at a maker's booth at a large RenFaire, several years ago. Sterling silver scrolled setting with authenticity hallmark inside band. Deep purple stone catches the light, cannot do it justice in photos. Excellent condition, no chips in stone. Size 8 Real silver will tarnish with time. A little silver polish will brighten this right up. Very mystical!
