Questa varietà brasiliana burattata favorisce il radicamento e la stabilità emotiva, ideale per chi cerca di rafforzare la propria connessione con la terra. È tradizionalmente associata all'equilibrio delle energie, al miglioramento della concentrazione e alla chiarezza mentale. La magnetite stimola inoltre la fiducia in se stessi e aiuta a dissipare le energie negative.
