Hi

    Michael R. Mathews sensibly asks whether the 'unfair' rhodium
    plating of yellow gold also applies to rhodium plated "off colored
    18K white gold". 

    This is a tricky one - as I've posted before, problems with some
    white gold alloys and the present avoidance of nickel (allergies) and
    zinc (brittless) mean that many white golds are 'off white' at best. 

    There has never, to my knowldege been any legal definition - or
    litigation - but the base line must surely be that customers should
    know what they are getting. They shouldn't be surprised when the
    rhodium wears off on the edges and a different colour is exposed. 

    ... of course, if the rhodium is not supposed to wear off, why have
    gold underneath at all? Why not brass? What useful purpose does the
    gold serve (other than ensuring a relatively high price)? :) 

Yours
Jack Ogden
