Some minerals exhibit electrical properties – for example, quartz is piezoelectric – but electrical properties are rarely used as diagnostic criteria for minerals because of incomplete data and natural variation. [95] Minerals can also be tested for taste or smell.
The classification of minerals is a process of determining to which of several groups minerals belong based on their chemical characteristics. Since the 1950s, this classification has been carried out by the International Mineralogical Association, which classifies minerals into the following broad classes: Classification of non-silicate minerals
The name of a new mineral is kept confidential by the IMA until it is approved or until its full description is published, its authors' option (approved decision: 'IMA2009-D'). [5] The IMA uses a code for its own procedures for the supposed new mineral (and so it is a synonym).

Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
Dana's classification [1] [2] is a mineral classification developed by James Dwight Dana. It is based on the chemical composition and structure of minerals. It is mainly used in English-speaking countries, especially in the United States. The mineral classification used by the International Mineralogical Association is the Nickel-Strunz ...
The Mohs Hardness Scale is the main scale to measure mineral hardness. Finger nail is 2.5, copper coin is 3.5, glass is 5.5 and steel is 6.5. Hardness scale is Talc is 1, Gypsum is 2, Calcite is 3, Fluorite is 4, Apatite is 5, Orthoclase Feldspar is 6, Quartz is 7, Topaz is 8, Corundum is 9 and Diamond is 10. Odor; Not always recommended.
This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties.
