it is hexagonal
Corundum is in the trigonal crystal system.
hexagonal crystal system ( 6 sided )
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.
Mercury, at solidification temperatures, is classified in the trigonal crystal system.
Knowing a mineral's crystal system helps researchers understand its atomic structure and physical qualities.
Gypsum and orthoclase feldspar are in the monoclinic crystal system.
plagioclase, microcline, rhodonite, turquoise, wollastonite, amblygonite, and many more.
Corundum is in the trigonal crystal system.

Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Six crystal classes are known.
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.
Three axes.
An example of a crystal ball question is "Does he love me?"
I believe the answer would be the crystal system, but the crystal system is based on the angles and length of the axis of the crystal. The axis length and the angle at which they meet would affact the number and angle of the crystal faces.
