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.

minerals get its crystal shape by the heating and pressure from rock
Crystal form refers to the natural geometric shape of a mineral crystal, which is determined by its atomic structure. Cleavage is the tendency of a mineral to break along distinct planes of weakness due to its internal atomic arrangement. Cleavage can be described in terms of the number of planes, angles between them, and the quality of the cleavage surface.
Yes, crystal shape is a physical property. It refers to the external geometric form that a crystal takes, which is determined by the arrangement of atoms within the crystal lattice. The shape of a crystal can provide information about its internal structure and symmetry.
When a mineral forms a definite shape, it is known as a crystal. Crystals are ordered arrangements of atoms or ions in a repeating pattern that gives them their characteristic shape. Crystal shape is determined by the internal arrangement of atoms within the mineral.
Gold does not have a defined crystal shape as it is a metallic element. However, under certain conditions, gold can form cubic, octahedral, or dodecahedral crystal shapes.
