Pyrite
Pyrite is an excellent energy shield. It blocks and cuts off the stream of negative energy at all levels.
It is a very positive rock, it stimulates our energy flows and facilitates our contact with our own skills. Psychologically, it reliefs anxiety and frustration. Pyrite empowers self-esteem and confidence, especially in men who feel inferior. In women, it helps overcome complacent attitudes, as well as the inferiority complex. It speeds up mental activity, memory retention, and remembrance capabilities.
