How early is too early to give a promise ring?

I’ve (15F) been in a relationship with my boyfriend (15M) for almost 9 months. Our one year anniversary is in late October, and I’d like to gift him a promise ring for it. This is the first relationship I’ve actually been happy in and I truly love this guy, but I don’t know if we are too young or if it’s too early. Can someone give me some advice?

Update: I ended up getting him the ring, I gave it to him the day after our anniversary because something came up the day of.

He cried when I read out the promises and he adored the ring, and turns out he got one for me too and gave it to me on Halloween, and I also cried lol.

Thanks y’all for sharing your opinions :)
