Crystals from minerals that belong to this class can be fascinating with their complex non-symmetrical faces. Unfortunately leucophanite does not show its true symmetry but exhibits an impostor symmetry, and a rather ordinary one at that. Leucophanite is named for the white flashes that are seen as a crystal is rotated. There are a few similar sounding minerals such as leucophoenicite , leucophosphite , leucosphenite and even leucite . But leucophanite is very different from all of these.
Color is white to yellowish, yellow and green.
Luster is vitreous. Specimens are translucent to transparent. Crystal System is triclinic, 1. Crystal Habits are pseudotetragonal and pseudocubic forming rectangular box or cube shaped crystals. Penetration twinning is common and forms flat square and elongated crystals.
