Amethyst Galleries THE TRIGONAL SYSTEM

This class, more so than the other classes of this system, has members that "borrow" forms from the more symmetrical hexagonal system's classes. In fact, unless a crystal from this class shows rhombohedral or scalenohedral faces or rhombohedral cleavage or parting, it will be difficult to determine the crystal's true symmetry.

Crystal system Wikipedia

A lattice system is a class of lattices with the same set of lattice point groups, which are subgroups of the arithmetic crystal 14 Bravais lattices are grouped into seven lattice systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic.. In a crystal system, a set of point groups and their corresponding space groups are assigned to a lattice system.
