Fluorite 
Fluorite is known to absorb and neutralises negative energy and different types of stress we all encounter. It's an excellent learning aid, that helps everyone increase their powers of concentration.
Fluorite also help people build their self-confidence as well as helping us make decisions more quickly or more easily, which is directly linked back to the part about self-confidence. They are interlinked. 
Fluorite encourages positivity, balances a person's energies, as well as improving your balance and coordination, both  mentally  and  physicallly. 

When working with the upper Chakras, Fluorite increases a persons intuitive abilities, links the human mind to a sort-of universal consciousness as well as developing your connection to the Spirit. It is known to help anchor a person's intuitive insights into the physical plane, thereby facilitating both mental and physical coordination as mentioned above.
