Since ancient times, pyramids have been considered powerful sacred structures. It is believed that a pyramid shape harnesses, amplifies and focuses higher vibrational energies through its apex. Because of its shape, a pyramid made from Shungite spreads its healing properties over a significant distance. Each pyramid is hand-cut. Shungite stone may have mineral inclusions (light streaks, spots or veins) that are primarily pyrite or iron oxide that naturally occur in Shungite, making each piece uniquely beautiful. Because of its high carbon content your new Shungite piece may shed some black residue on skin, clothing or other surfaces. This is normal and harmless. The residue can easily be washed off most surfaces. Wiping the object with a soft damp cloth will remove any loose carbon dust and minimize this effect. See "Sizes" for the effective influence radius of different pyramids. Learn more about SHUNGITE here, and about SHUNGITE's EMF properties here. AUTHENTICITY
