Three axes.
I did a degree in geology, many years ago now, the complexities of this are enormous, and you could probably spend a lifetime investigating. If you are interested then it is worth exploring, some minerals look wonderful in thin section down a microscope where you can see some of the planes they will fracture on amongst many other things. But it seems i have forgotten more than i can remember right now!

Quartz has many different habits, but only one crystal system category, trigonal, and one formula, SiO2. The various forms of quartz are a product of their method of formation or exposure to radiation or impurities. Some forms are agate, chalcedony, jasper, amethyst, chert, rose, citrine, smoky, milky, moss, flint, Cat's Eye, Tiger Eye, prase, carnelian, rock crystal, and aventurine.
Potassium iodide crystals have many uses:supplement added to table salt to prevent goitertablets taken to protect the thyroid from iodine-131 radioactivity in falloutradiation detection crystal in some scintillation countersetc.
== == Many minerals have multiple crystal habits, which are the size and shape of a particular mineral crystals formation. Examples of crystal habit include boytroidal, stubby, blocky, radiating, wheat sheaf, columnar, acicular, foliated, subhedral, euhedral, drusy, dendritic, and bladed.
plagioclase, microcline, rhodonite, turquoise, wollastonite, amblygonite, and many more.

Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.

There are infinitely many axes of symmetry in mathematics.
infinite number of axes
a hexagon has 4 axes ofsymmetry.
a rectangle has 2 axes of symmetry
2 axes from angles to angles
It has 5 axes of symmetry
A square has 4 axes of symmetry.
