what should I get him?

Grace
He is getting me a ring for our 6 months. ( our limit is $30 but Im fine with spending a little more)
But I have no idea what to get him for him to wear/ think about me with.
He isn't a ring guy:/ Which I understand. 
He is getting one of these rings for me 😍. I love him so much and want him to know that. Any ideas on what I could get him? ( I got him a wallet and a blanket for Christmas but I want something more special)
