They also can form when loose grains are cemented together, forming a clastic rock, such as sandstone. Most minerals are naturally occurring homogeneous geological substances that are stable at Earth-surface conditions. . Instead, they are amorphous solids, meaning they contain a random arrangement of atoms. 1. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. However some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite).Moreover, living beings often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks.. The different colors stem from very small compositional differences; all beryl is essentially Be3Al2Si6O18.

Crystalline rocks may form from a magma (e.g., granite), may form by metamorphism (e.g., gneiss), or may form by precipitation from water (e.g., gypsum). And, because zeolites are natural sieves and sorbents, synthetic zeolites are used in water softeners, and in chemical manufacturing processes. Light emitting diodes (LEDs) are commonplace in TV screens, light bulbs, and other devices. Colourways; Coordinates; Topaz – Amber.
