Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO₄ silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂. Wikipedia
Natural clear quartz has a smooth-sided, prismatic hexagon shape. They may have facetted terminations at one or both ends. The shape of the termination facets is determined by how quickly the quartz crystals are formed.
