Opalite
 
Unlike many other crystals, Opalite is a man-made stone created from glass. As such, it has a far different meaning for spiritual purposes compared to other, natural stones coming from the Earth.
Helps to balance the yin-yang energies, and help to align them with the individual’s higher self. This can help control mood swings, by making an individual feel more anchored, and it can eliminate blockages in the energy meridians and chakras. Opalite is a stone of personal power, known to increase self-esteem and improve one's sense of self-worth. Along with these empowering qualities, it also engenders the related quality of inner strength to uncover and express one's deeper, more buried feelings.
