Carnelian — A stabilizing stone with high energy. It is excellent for restoring vitality and motivation, and for stimulating creativity. Carnelian sharpens concentration and dispels mental lethargy. Emotionally, it is a powerful protector against envy, rage, and resentment—whether your own or from others. It calms anger and banishes emotional negativity, replacing it with a renewed love of life.
