For our anniversary in February, I bought my girlfriend jewelry from Tiffany's. I myself have a couple of Tiffany's pieces and thought they were pretty high quality. I spent around $250 on a sterling silver necklace and she's been wearing it every day; she has yet to take it off. Now it's end of May and the thing is starting to tarnish really badly-- the pendant as well as the chain. My gf wears a lot of rings, all of them sterling silver (most of them cost under $30), all the time without taking them off, and they haven't tarnished at all over the years.
WHY IS THIS EXPENSIVE PIECE OF CRAP TURNING BLACK?
