This is not a casting. This ring is hand forged from a single piece of brass using traditional blacksmithing techniques of fire, hammer and anvil. The outside is heavily distressed and textured using a rough edge of a hundred year old anvil. The inside of the ring has been sanded and polished to ensure a comfortable fit.
REGARDING OXIDATION, PLEASE READ: Brass is a copper alloy. It is common for copper to react with skin producing a temporary green discolouration of your finger. If you're worried at all about skin discoloration, please do not purchase this ring. Per request, I can add a transparent coating of Everbrite Protectaclear which will help to avoid skin discoloration. This coating will eventually wear off.
