Weird. I never ever heard of putting your birthstone in your class ring. It's a class ring, not a birth ring. It's not about your birth month, it's about showing you are part of your class. At our school we didn't have a choice, everyone had to have the simulated ruby. We all wanted to be alike to show we were a part of our school. If I wanted a saphire or emerald than I would have bought a different piece of jewlery for that, but I was proud to be part of my school and part of my class. A couple of girls that wanted to be different went to different jewelers to pick a smaller more feminine setting. But they still went with ruby and the class shield.
