These rings are all made of 12-gauge copper. Each of the rings were hammered in different textures and then treated with sulfur to achieve the antiqued finish and to bring out the details on the rings. Take note that the ring will develop patina as you wear them. This is because the copper does not have a coating or wax, as I wanted to preserve its healthy benefits for the wearer. Please let me know if you want them to be varnished.
If the item develops patina, you can clean it by dipping it in a solution of warm water with a tsp. of salt. Squeeze a lemon and add a few drops to the solution. Submerge the item in the solution for a few minutes and rinse it afterwards. Some of the patina should come off.
