Theory

This is general theory, but before I theorize I will go with some facts. The diamond can be used to focus the thought energy into ice. The ruby is the thought energy goes and becomes fire. Now the theory. The theory behind this is simple, the composition of the gemstone creates the effects that I just mentioned.  The ruby in particular, you can create fires in a campfire. This is where you could freeze the fire by a diamond or use water molecules in the air to freeze around a target.

This reminds me to always have a ruby or diamond on me given the reason that things could work out that I would need them. So I will ciou and farewell till later, good-bye.
