It's possibly a naive question with either a very easy or no easy answer, but does anyone have any idea who makes jewelry for Argos, H.Samuel, Beaverbrooks, Goldsmiths et al? I'm guessing that they may use different manufacturers for different parts of their range, but is most of the work done overseas now, and if so where? And if a customer buys a ring from them and requests it to be resized before taking it away, or a customer goes to them wanting some kind of repair, who do they give the work to then? Will they all have an in-house team that does this kind of work or do they routinely out-source it, and if so to whom?
