Crystal Card of the Day: Lithium Quartz, "I release any unwanted energies and allow myself to heal." Lithium Quartz Crystal is pure clear quartz with inclusions of magenta-colored Lithium ions. The Lithium contained in this Quartz is the same mineral used in antidepressant medication, but in its pure form as it comes out of the Earth. When combined with Clear Quartz, the natural antidepressant properties of Lithium are amplified. It brings emotional peace, stress release, and relaxation.
