I also think it's the tenrou jade,which chooses a wizard and teaches/increases magic within a wizard of it's choosing.In FT:zero it is said that mavis tries to learn magic,maybe she finds the jade and it contains a spirit(not a celestial spirit)that teaches her magic like detternt magic example:fairy glitter and fairy sphere or it might just contain one magic.Ever wonder how/who taught zeref magic?.Both of them may have learnt magic from lumen histoire.
