Wearing a Tiffany and Co necklace to college?

I am entering my first year in college. Last year I saved up for a 400 euro Tiffany and co necklace that has its name and a diamond on it. I bought it from Paris when I went there to visit my sister. So I have been thinking about it. I mean its not over the top, its just a necklace with an average diamond on it but it has tiffany and co on it and its pretty noticeable. Now I am considering if a tiffany and co golden charm would be OK to wear to school. Or do you think that would give the wrong impression to people?
