A random gem I drew.

I was trying to fit a spirit around it, as if it was an energy stone the spirit drew off of to materialize itself, but that didn't quite work out, lol.

I have decided that it is a power gem, of the fire element, used to power fire spells, or fire golems.

I've also been playing Megaman 64 recently, I think it was really influenced by their refractors.

EDIT: A friend asked for all the elemental gems, so we have fire, air, earth, water, ice, and thunder gems.
