Hi, I have carved a pendant design that looks like an upside down fan, spread out in a semicircle, with five folds,it has been cast in 950 Palladium, finished and hallmarked, I want to yellow gold plate the centre sail front and back to create the illusion that the middle bit is gold but have been advised by a metal plater, only after I sent it that it isn't possible, does anyone know different or is it indeed not possible?
