Springtown
We have chosen the name of a colorful Gold Rush boomtown for mankind's original ring: A piece of metal, hammered out into a wire and wrapped around the finger.
Rings similar to this have been discovered in ancient burial sites of many different cultures like Inka(Inca), Celtic, Norse, Mongolian to name a few. Archaeological museums have examples in varieties of metals.
Some ancient cultures used these coils as trade currency. The coils have been created for the California culture in its "native son" of minerals by Todd Bracken. Only available up to size 10.
