Each stone and crystal has metaphysical properties that can help aid in specific situations, help boost certain body functions/body parts, and can even offer different insight into the seen and unseen world around us.

Rose Quartz: Is a stone of the heart and unconditional love. It carries a soft yet strong feminine energy of compassion, peace, tenderness, healing, nourishment, and comfort. It speaks directly to the Heart Chakra, dissolving emotional wounds, fears, and resentments, while circulating a divine loving energy throughout the entire aura and body.  Rose Quartz is also known as the love stone.
