I am guessing not - as they take no real wear impacts like rings - but I have to ask - we have a set of 3/4 carat diamond earrings - 8 stones each ring - 14Kt Yellow Gold - kind of a double prong setting in a hoop - basically 5 pointers each - bought them from a large retailer last Christmas - wife never worn them - and decided she would prefer they were white gold - but even with the receipt, original box, and clearly never worn - the retailer offered no solution given that it has been 4 months since purchase - so other than reset them - which does not seem cost effective (but I have not checked that out - I am just guessing that if I could even find a suitable blank - the cost of the blank and the labor would make it where I should just sell them on EBAY and buy new White Gold from the start) - we are a bit stuck - was actually thinking of just rodium plating them and seeing how long the plating would last on such earrings that would be worn probably 5 times per month - guessing the plating would not wear away with them just sitting in the jewelry box - but I know little about this sort of thing -
