I was only asking because I tried on the same bracelet but it looked like it needed to be polished

Oh ok! Well this Yurman bracelet (the left chunky one) I bought a few months ago was tarnished at the store but when I purchased it the SA polished it and told me that it can happen when it's been sitting in the case. I mentioned that I will be wearing it everyday (which I have been) and she mentioned that if I do that, I won't really need to polish it and I haven't yet. I have never taken that one off since I purchased it a few months ago.
