Hi,
I've discovered a cartoons series, it is a little old but characters and story are still great.
The evil Queen Idun steals the blue crystal and with its power she transforms from an old hag to a beautiful young woman.
I've posted two link, before and after the process, because there are scenes in between.
Unfortunately it is in Spanish and I don't know if there is an English version.

I hope you enjoy it!
