In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.
Saiph is a supergiant with a stellar classification of B0.5 Ia. The luminosity class ‘Ia’ represents a bright supergiant star that has exhausted the supply of hydrogen at its core and evolved away from the main sequence.
The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale.
