Cubic Zirconia is a man-made crystal. It helps in meditation. When placed under the pillow, it can be very helpful in directing one toward discernment. While clear cubic zirconia has a very sharp, strong energy, the pink version of the crystal is much softer, warmer, and not as easy to figure out. There is a greater sense of latent power in it, whereas the clear crystal keeps its power very much front and center.
