I've had this flower necklace for a good 10-15 years. It's sterling silver and was always "oxidised", as in it was greyish when I bought it. I stopped wearing it as it got so black, and I was nervous about cleaning it as it was supposed to have some degree of tarnish and I didn't want to totally ruin it. I've just decided to get it back out and give it a good clean, rather than never wear it again. It has come up fairly well, but I can't remember what it actually looked like in the first place! Does it still look too black? It's pictured here next to a bracelet that isn't tarnished, though I know the lighting isn't good!
