== == Pyrite is iron sulfide, a mineral composed of sulfur and iron. It's also known as "Fools'Gold" because of its shiny yellowish metallic luster. Pyrite can be found in sedimentary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron.Pyrite is sometimes an ore of gold and copper. It is also an ore of sulfur, which is used in the production of tires, explosives, disinfectants, medicines, ink, wood preservatives, dyes, matches, and sulfuric acid. Some collector specimens can be quite valuable as well. The streak of pyrite is greenish-black. Pyrite is in the cubic/isometric crystal system where three axes running through the center of the crystal are of equal length and form an angle of 90 degrees at intersection.
Schist typically belongs to the metamorphic category of minerals and does not have a specific crystal system since it is a foliated rock composed mainly of micaceous minerals. However, the individual minerals within schist, such as muscovite and biotite, usually belong to the monoclinic or hexagonal crystal systems. The foliation in schist is a result of the alignment of these plate-like minerals under directed pressure and temperature conditions during metamorphism.
Amethyst is a variety of quartz, which crystallizes in the trigonal system. Its crystal structure is characterized by a hexagonal arrangement of silicon and oxygen atoms, forming a continuous framework of SiO₂ (silicon dioxide). The purple color of amethyst is due to the presence of trace amounts of iron and other impurities, which can create color centers in the crystal lattice. Overall, its unique structure contributes to its beauty and popularity as a gemstone.

Triclinic is a crystal system that describes the geometric arrangement of atoms in a mineral. Minerals can belong to different crystal systems, such as triclinic, depending on their internal structure and external crystal shape. So, a mineral can have a triclinic crystal structure, but triclinic itself is not a mineral.

A triclinic crystal system has three unequal crystallographic axes that intersect at oblique angles.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Yes, the crystal system a mineral belongs to is a property of a mineral.
Atoms within a mineral are arranged into an orderly geometric spatial arrangement known as crystal structure. There are 14 basic crystal lattices (refered to as the Bravais lattices) which fit into one of 7 crystal system (triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal and cubic) and all observed minerals fit into one crystal lattice and one crystal system. Diamond on the other hand is an allotrope of carbon arranged into an isometric hexoctahedral (Cubic-type) crystal system.
It is a system of classification of crystals into 7 crystal systems(Cubic,Tetragonal,Othorgonal,Hexagonal,Trigonal.Monoclinic and Triclinic) on the basis of their Geometrical properties and symmetry (Diads,Triads,Tetrads,Planes of symmetry,Centre of symmetry)
Six crystal classes are known.
Sulfur is an example of a mineral that crystallizes in an orthorhombic crystal system. Its atoms are arranged in a structure with three mutually perpendicular axes of differing lengths.
The crystal system a mineral belongs to relates most to the mineral's internal atomic structure and arrangement of atoms. This determines the shape and physical properties of the mineral, such as its cleavage, hardness, and color.

Diamond is one mineral in the isometric crystal system.
