Believed to be one of the best mood stabilizers in the world of gemstones, the Lepidolite crystal contains a high amount of Lithium, which is also used in anti-anxiety medication. It doesn't require a prescription and side effects may include a sense of calm and tranquility during times of stress and chaos. Wizards often use their pieces of Lepidolite to balance not only the mind, but also the spirit. As Wizards are know for being quick to temper, this stone is a helpful one, especially when you need to cool off any potentially fiery emotions.
