This is a great ring to consider for a wedding or anniversary band. The stones sit a little sunken into the band so they are protected from everyday wear and tear. This particular ring features three tourmalines; they were all mined at Mt. Mica in Paris, ME. They measure 2.5 mm and weigh .18 total carats. The ring is sterling silver. Ring setting designed in and created by Columbia Gem House of Vancouver, WA. We do have the same setting set with other configurations; please contact us for more info!
