This listing is for one ring of your choice. These rings are made with copper. All rings are dipped in a protective clear lacquer to help preserve the color of the metal and reduce color changes to skin. Copper naturally oxidizes and will eventually tarnish and may cause your finger to turn green where the metal touches your skin. This discoloration is natural, non-harmful, and is due to the oxidation of copper. These rings are not recommended for anyone with metal allergies. Disclaimer: Colors may vary slightly from photos.
