A pyramid is a geometric solid that has a polygon as its base and faces that converge at a point called the apex. Cones are similar to pyramids except that their bases are circles instead of polygons. Spheres are solids that are perfectly round and look the same from any direction. This mighty stone formed part of an outer layer of fine white limestone that would have made the sides completely smooth. It was polished until it shone so that the pyramid would have gleamed in the sun. Pyramids help in absorbing negative energy and blockages from the chakras. They help in meditation and healing. We have a wide range of pyramids made from various stone such as amethyst, agate, apophyllite, crystals, etc.
