I have been wondering about the use of metals such as copper, brass and bronze in “fine jewellery”. I know this isn’t technically possible as the definition of “fine jewellery” is that it must be made with precious metals but if a piece of copper is cast into an ingot mold, rolled to bar stock and then made into a ring could this really count as worthless “fashion jewellery”? It’s 100% handmade but is made from a base metal. What would this count as? Is it even possible to make “fine jewellery” from brass, bronze and copper? If so, is there a market for it? At metals below the cost of gold, most of the cost is labour. That being true would mean a bronze ring would cost nearly the same as an equivalent ring in silver. The difference being the silver ring is “fine jewellery” and the bronze one is “fashion Jewellery”. Sure the bronze would tarnish faster and turn your finger green but both would last a similar amount of time. I don’t know, copper and it’s alloys seem like nice metals, and if handmade would last a similar amount of time. Is the only thing preventing handmade copper jewellery from being considered “fine jewellery” it’s status as base metal?
