The purpose of drinking water with any crystal in it is for metaphysical & spiritual healing. If you believe in that. I do. Different crystals have different healing frequencies. Rose quartz promotes unconditional self-love. You can google each crystal & what they are used for. You are getting the healing energy from that crystal in the water you ingest into your body. If you put a high PH or Spring water in your water bottle, that’s better for you but everyone is different & that is only my opinion.
