A crystal pyramid has four sides and a base. If found in its natural formation, the base may be squared off. Apophyllite has naturally forming pyramid shaped crystals which tightly focuses energy through the apex. Such crystals are good for manifesting. Pyramids can be formed within your mind over your home, a room, your workplace, your car or yourself. Pyramids have been used as a mode of protection since ancient times and continue to be a popular and easy way of putting up a protective barrier around yourself or a larger area.
