This one is from the same trip unstamped--got the kit to test it and sure enough. A clue that they told me at the refinery is that PLAT will scrach white where as white gold will scratch yellow. My jeweler also says to feel for ":double weight". Its about a $700 peice. Pictures getting only slightly better --I'm sorry.
