I'm having one of my designs cast, no problem with the silver version but I can also get it made in brass which I will get gold plated but...its got rub over settings that I will set faceted stones into. If I send for plating before I set the stones then I will damage the plating when I rub over the collet but I dont want to make a fool of myself taking a stone set item for plating if thats not how its done. One of the problems I guess of not having any formal training but I'm sure someone on this forum may be able to help
