You're wanting satin brass, not "champagne". Then.....I'd look at circa lighting regarding sconces. They need not match exactly.....just blend very well.. The mirror is easier as ANY good framer will have a thousand molding to choose from. Custom size/finish is the answer on that and far less expensive than you imagine. Below for example. Same idea applies in a more traditional application if that's the desire. Below a Kohler "purist" faucet, Circa lighting/Kelly Wearstler sconce.
