Wow. It looks like our worlds do share similar views on gems, how fascinating indeed. Although I don’t know if Earth people has ever used gems for magical purposes that often outside of myths and ancient civilizations and tribes. It would made for some interesting magical experiments.

Crystals on the other hand, I’m interested in how your world use them. I could guess that they have such powerful properties that people would want to get their hands on to cast all kinds of magics in your world.
