This powerful magical device is a classic tool for use in divination spells as well as a potent aid in meditation. Within, to aid you in your spell work and meditative contemplation of the chakras, you will find a rainbow of colors coalescing as though part of the Auroras that appear in night skies. Measuring 50mm, or approximately 1 7/8" in diameter, this lovely crystal ball is made of 60% leaded glass and 40% crystal.
