I chose a saphire because I liked blue. Not my birthstone or one of my school colors. If they don't like it, they won't wear it, so I'd let her choose what stone she wants.
For a CLASS RING, I don't see why anyone would choose anything other than the school colors. It's a symbol of your school.
If you want to choose your birthstone or your favorite color, why not go with any old ring that you like? It'll cost considerably less.
One stone only......garnet. A birthstone would have been unheard of. I think it still it.
So that's what I went for! I was the envy of every senior girl who was forced to sport a monster-heavy ring.
