Lithium Quartz - 

This is a stone that brings emotional peace, a release of stress and is a powerful yet gentle healer. The lithium contained in the quartz is the same mineral used in stabilizing medications and the amplifying qualities of the quartz crystal creates a perfect conduit for the antidepressant properties of natural occurring lithium to ease insomnia, anxiety and panic disorders. This calming duel stone gently moves repressed anger and grief to the surface so the healing process can begin.
