Will a sterling silver ring coated with 18K platinum last?

Question

or will the platinum coating eventually fade away?

Answer 1

It depends on how much wear your ring gets and on the thickness of the plating as to how long it will last but it is going to wear off at some time without question. Silver items, because of their relatively low value, are very rarely given anything more than the thinnest coating of platinum which rubs off very quickly, it is only put on to keep the item looking smart for a while and to act as a selling point to make the item sound better than it really is. Do not worry about it, even when the platinum comes off the ring will still look very much the same, the only difference being that you might have to polish it from time to time if the silver tarnishes.
