I have a diamond watchband that is 14K white gold I bought about 20 years ago. The diamonds are small-I think single cuts so there is more metal than diamonds. The white gold now looks slightly off color- paleish brassy color. I would like to replate it but wondered if the diamonds have to be removed before replating. I hardly wear the watch anymore and frankly do not know how much it should cost. But if the diamonds have to be removed and then reset I am certain that it will be fairly expensive. Any thoughts, comments and suggestions?
