Mineras are non-living constitutes of the earth's crust in the crystalline form which includes elements,compounds and mixtures that have definite range of chemical composition and properties.This are inorganic in nature.Some of the minerals are Bauxite,Dolomite,Crystalline.
Minerals can be classified in terms of structure and composition.This minerals are classified into many groups.These minerals are found in different countries with different minerals. These minerals are very valauable in nature.They are very costly.

physical properties :
- Crystal structure and habit:A crystal structure is the orderly geometric spatial arrangement of atoms the internal structure of a mineral.A mineral may show good crystal habit or form,or it may be massive,granular or compact.We can only see with the help of microscope. This crystal structure is based on regular internal atomic or ionic arrangement that is expressed in the geometric form that the crystal takes.Chemistry and crystal both this define a mineral.
- Hardness:The physical hardness of a mineral is usally measured according to the mohs scale.This scale is relative and goes from 1 to 10.Minerals with a given mohs hardness can scratch the surface of any minerals that has a lower hardness than itself
