As the"The Stone of Unconditional Love", it really has it's work cut out for it, which is why it needs to be discharged under running water once a week.
It helps release unexpressed emotions and deep seated heart ache while drawing in love and harmony. It's a helpful stone to have during traumatic times and is especially good for mid-life crisis as it stabilizes emotions and allows one to look at circumstances objectively.
My go to meditation stone to figure out where I am holding onto negative emotion, I hold it while inhaling deeply, then after exhaling all the air from my lungs, I stay in that stillness for a few beats and allow my body to tell me it is feeling blocked. Then I inhale deeply into the block, holding the stone over the area.
