Rings and nail polish?

I’m getting two rings from Pandora (as shown in the pic) and I read online that it turned some people’s finger green, and other reviews were saying that the color started fading soon after they got it. Do you think I could put clear nail polish over the rings? It’ll be like a protective coat. And will it still look good even over the diamonds, it shouldn’t really make a difference since it’ll be clear, right? Any advice will help!!!
