Six crystal classes are known.
Minerals are classified by their geometry into six different mineral crystal systems. Each crystal system has its own set of parameters based on relationships between length and angles between a crystals axes.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Three axes.
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.
Diamond is one mineral in the isometric crystal system.
Mercury, at solidification temperatures, is classified in the trigonal crystal system.
Minerals are classified by their geometry into six different mineral crystal systems. Each crystal system has its own set of parameters based on relationships between length and angles between a crystals axes.
Corundum is in the trigonal crystal system.
hexagonal crystal system ( 6 sided )
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Gypsum and orthoclase feldspar are in the monoclinic crystal system.
Three axes.
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.
Diamond is one mineral in the isometric crystal system.
Peridot (gem quality olivine (the mineral)) is in the orthorhombic crystal system.
monoclinic
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.
