Fluorite - A crystal that absorbs and neutralises negative energy and stress. An excellent learning aid, Fluorite increases our powers of concentration, self-confidence and helps us in decision-making. It encourages positivity, balances the energies, and improves balance and coordination, both physically and mentally.
 
Why skulls? When crystals are shaped into skull form, they will have key principles of sacred geometry integrated into them, amplifying their qualities exponentially. Crystal Skulls helps one to boost their psychic power! Crystal skulls does not mean death! Instead, it means how things within us do not change even when everything else around us does. 

Have a chat with me if you need help with recommendations on what crystals to get. :-)
