These rings will make great gift for yourself or for someone special. I make my rings from reclaimed copper and etch them with my own designs. The rings have not been sealed except for the cobalt blue and turquoise rings. Leaving them unsealed allows them to develop a natural, rustic and organic patina. However, they may be polished with a soft cloth to bring back to life the beautiful copper tones. The cobalt blue and turquoise rings are also made from copper but have had a very special patina applied to the surface to create the beautiful cobalt blue and turquoise colors. They have been sealed with an acrylic sealer to preserve the patina. In addition, the copper rings have been fired to allow them to be flexible enough to adjust to your finger. If you would like to purchase one or simply have questions please feel free to contact me.
