Replying to Go Pro scratch help

Sooooo on my go pro there is a scratch on the lens. I dont mean the plastic housing I mean the actual lens. I dropped it by accident when I was taking the camera out and this scratch is annoying as fuck and leaves a little white blur in the video. I emailed go pro asking if they can fix it and they said they could not because it is part of the camera. I dont wanna spend the money for a new camera so do you guys know any ways to fix the scratch or make it less visible? One of my friends said maybe take it to a jewlery store and they could buff it out but idk if that works. +k for quality answers!
