Carnelian is a stabilizing stone with high energy. It is excellent for restoring vitality and motivation, and for stimulating creativity. It sharpens concentration and dispels mental lethargy. Emotionally, this stone is a powerful protector against envy, rage, and resentment, yours or other people's. It calms anger and banishes emotional negativity, replacing it with a love of life.
