By size, and geometry, by their structure in one of the six mineral crystal systems.
Geologists classify crystal structures based on the arrangement of atoms within the crystal lattice, the symmetry of the crystal, and the types of bonds between atoms. Common crystal structures include cubic, tetragonal, orthorhombic, monoclinic, and triclinic structures.

By definition, a mineral must have a crystal structure.
A mineral crystal is not necessarily a diamond, but a diamond is a mineral crystal. All minerals, such as diamond, have crystalline structures.
Crystals of minerals are classified based on their internal atomic arrangement and external geometric shape. This classification system is known as crystallography, which considers factors like symmetry, cleavage, and atomic structure to categorize crystals into different mineral groups such as cubic, tetragonal, orthorhombic, hexagonal, and trigonal. This classification helps in identifying and distinguishing different minerals based on their unique crystal properties.
crystal structure
The genetic information, morphological structures and the fossil records are some of the required information required in order to classify the animals.
Solid oxygen has crystalline structures.
Octahedral holes in crystal structures are important because they provide spaces where certain atoms or ions can fit, helping to stabilize the overall structure of the crystal. These holes play a key role in determining the physical and chemical properties of the crystal, such as its density, hardness, and conductivity.
NaCl is crystal-shaped because they are ionically bonded, and all ionic bonds make hard, but brittle crystal structures.
Hydrogen gas (H2) does not exhibit a crystal structure at standard conditions because it is a gas composed of diatomic molecules. In order for hydrogen to form a crystal structure, it needs to be in a solid form, such as solid hydrogen which exhibits different crystal structures depending on the temperature and pressure conditions.
Minerals form crystal structures.
