triclinic

It is triclinic, has one direction of perfect cleavage, and may be white, yellow or green.

A triclinic crystal is shaped almost like a rectangle.

Reddish-brown to black triclinic aenigmatite occurs also in these rocks.

Triclinic crystals can show as many as three colors.

The related mineral parahopeite, which has the same composition but different crystal structure, is triclinic.

Also the whole parallelepiped has point symmetry C (see also triclinic).

Its crystal system is proven to be triclinic via X-ray diffraction testing.

Hemozoin crystals have a distinct triclinic structure and are weakly magnetic.

Amarantite is triclinic, which means crystallographically, it has only one symmetry fold.
