What are minerals?
Minerals are naturally occurring elements or compounds. Most are inorganic solids (apart from liquid mercury and a few organic minerals) and defined by their chemical composition and crystal structure. By weight, 99.5 per cent of minerals are formed from only 12 of the natural elements. Clearly, some elements are far more common than others.Web

Quartz. Quartz is one of the most common minerals in the Earth's crust. It is made of silicon dioxide (SiO2), otherwise known as silica. Varieties of quartz based on color include: amethyst (purple), smoky quartz (grey), rose quartz (pink), and citrine (yellow-green). Quartz has a glassy luster and a hardness of 7.Web

Similarly, some minerals have different chemical compositions but the same crystal structure. For example, halite (made from sodium and chlorine), galena (made from lead and sulfur), and periclase (made from magnesium and oxygen) share the same cubic crystal structure. Crystal structure greatly influences a mineral's physical properties.Web
