Is there really much of a concern with diamonds in platinum settings? I had thought that the sonic cleaner from (I'm blanking on the store name) that was posted earlier would have been safe. Now I'm curious what the concern is...----------------
To be on the safe side, don't let anyone but your jeweler use sonic or steam cleaning on any jewelry. Some gemstones, like emeralds, should not be subjected to sonic cleaning or may not tolerate the heat.
