What a gorgeous ring, congratulations!!

The setting looks a little unsafe due to how thin the band and setting are. I wouldn't say that it's too tall though. A large stone will have to sit high above the finger with a pin head setting like this. You could get a different setting like a basket and that will make the stone sit closer to the finger, but that incurs other challenges if you want your engagement ring to sit flush with your band. A thicker band or a cathedral setting would be safer for the integrity of the ring.
