The necklace arrived and was completely tarnished and a greenish/black upon opening it. It took me 20 minutes to try to polish it, and it's still not great. The necklace has meaning for me so I'm keeping the key pendant, but I'm buying a replacement chain from another store and throwing out the tarnished one. I was really disappointed because this necklace means a lot to me, I used to have the same one as a child.
