no problem I don't think any of them are stamped with anything on them I have other pendants listed, now I have had them a while and they have never turned colors and I have necklaces from this same supplier that I wear and they do not turn colors when I wear them and my skin is super sensitive as long as I wear it for the evening and take it off I am ok.
if i win it..itll go into my box of pins and pin backs for a rainy day when i need credits ..lol..like i need more stuff,it seems like im getting rid of things and replacing it with more stuff i dont need,hope all is going well with you
