ER white gold and scratched

Hi all, last week my boyfriend proposed to me me with the ring we chose together. It's a blue topaz with diamonds in a 9ct white gold band. I've only worn it a week and today I noticed the underside of the band had lots of fine scratches on it. Is this normal? I'm really anxious about the ring now and if it looks like this after a week what will it look like in ten years?! I've been super careful with it too as it's new on and I'm very aware of its presence. Any advice or tips greatly appreciated!!
