As far as I'm concerned, your brother is not a little kid anymore and he should be given rather weighty and expensive gifts. For my 19th birthday, I got a game console. But my friends didn't know that I wanted mens diamond pinky rings . These rings look very elegant. I wanted to look like some villain in a movie who wears a diamond ring on his little finger. But soon I will save money and my dream will come true. So I think you should give him a piece of jewelry like that.
