men's promise rings

What do you ladies think about getting your man a promise ring? Or a ring in general to symbolize commitment and promise of a future together? To me I've honestly never thought about it until I met my boyfriend. It's been a year and with everything we have been through together I know one day I'm going to marry this man. I was thinking about getting it as one of his Christmas presents. I just don't know if he'll appreciate it as much as clothes or paraphimilla or if it's selfish of me to do so, (he's hinted about an ounce of weed lmao). I just don't want to disappoint him. I really care about him and want to give him something to show my commitment and love to him. I'm just torn and looking for opinions and advice
