My Tiffany And Co Bracelet Is Turning Colors.?

It almost looks like the silver is coming off and there is a pinkish color underneath right on the clasp. I know it is real and I was with my mom when she got it a few years ago. She gave it to me a couple months ago… Now that I have it it is turning colors. She said it is because I never take it off and it is not meant to be worn daily. Is that true?
