Recycled Silver tension ring This silver ring is wrapped, meaning the tension of the metal is what makes it keep its form. This ring can be worn by a man or a woman, its width making it perfect for the middle finger. The ring is 8mm wide and made of 1mm thick sterling silver. In its current size the ring is 3mm thick, but this could change if resized. It is an American 7, a European 14 (54mm finger circumference) and a British N1/2. Because it is not soldered this means it is easily adjustable up to 1 1/2 American, 3 1/2 British or 4 European sizes larger. When checking ring size always use a ring of similar width as this affects the size.

All my metal is from a company which is a member of the Responsible Jewelry Council. They deal only in recycled silver and gold. They smelt their metals to the highest environmental standards, to cause the least impact on the environment. They do not deal with newly mined metals, as these metals cause much greater destruction to the environment.
