I have been unable to find platinum ring wraps, but I have talked to several jewelers, and they tell me that it is just as good to use a white gold wrap as to use platinum. They look identical in appearance. Actually platinum is not as durable as white gold. It tends to scratch and dull more easily than that of gold. I have looked at several platinum rings, and they look the same in the store, but after wearing them for a long period of time, they tend to lose their shine. So, getting a white gold wrap to accent your diamond would not be a noticeable difference. Of course, if one is demanding platinum because it is platinum and not white gold, I would suggest taking your ring and having a custom made ring wrap for it.
