Kendra Scott review: jewelry

I'm disappointed in Kendra Scott. I take very good care of my jewelry but it seems like my Kendra Scott loses its coloring. The silver fades to a tarnish color. It's says that you should wear perfumes or lotions with your jewelry. So basically you're saying your product is cheap and will be no good if anything touches it. I have other costume jewelry that does not do this and I paid less.
