Bought this several months ago, love it despite the fact I have to use an extender to wear it. I won't, however, be wearing it now. Haven't worn it in the last month, had it in a Prestige box -- and it has turned a copper color. Nothing else in the Prestige box is affected the way this necklace has been. Interested to know if anyone else has had Technibond not just "tarnish," but turn this awful coppery/bronze color.
