Protects from negativity and fosters the wise use of power. the meaning has been attributed to one’s own power and control, psychological or physical including the self limitation. It is said to be capable of discharging any amount of negative energy, and able to keep these energies away from the surroundings of the wearer. It’s a calming and strengthening stone!
It’s useful to clear energies which might be stuck in your Yoni. My personal recommendation: especially helpful after destructive relationships
