Diamond is one mineral in the isometric crystal system.
Gypsum and orthoclase feldspar are in the monoclinic crystal system.
Quartz is a crystalline mineral that typically forms in a hexagonal crystal system. Its most common form, known as alpha quartz, exhibits a six-sided prism shape with a hexagonal cross-section. However, quartz can also exhibit other forms and variations, but its fundamental crystal structure is hexagonal.
Pearls are not crystalline and don't have a crystal shape.

Agate, being a cryptocrystalline (microscopic crystal structure) form of quartz, does not have a crystal shape.
Quartz is a crystal form of silicon dioxide, SiO2. The silicon dioxide has a tetrahedral shape, in quartz each oxygen is shared by two tetrahedra.
Magnetite is in the isometric crystal system where the crystal axes are the same length and at right angles to each other.
Crystal systems are the way in which unit cells are categorized according to their axial and dimensional symmetry while crystal structure refers to size, shape, and atomic arrangement within the lattice.
minerals get its crystal shape by the heating and pressure from rock
Crystal Symmetry is the ability of a crystal to shape by nature and has a symmetrical shape. It's also referred about the occupation of diamond cutters.
