Lévyne crystallizes in the trigonal crystal system and belongs to the hexagonal scalenohedral crystal class. It typically occurs as radiating clusters or fibrous masses that are transparent to translucent in colors ranging from white through reddish and yellowish white to gray. It has a specific gravity of 2.09 - 2.16 and a Mohs hardness of 4.0 to 4.5. It has a vitreous luster and perfect cleavage on [1011]. Typical occurrence is as an alteration and vesicle filling mineral in basalts.
