The term "trigonal" stands for a threefold rotational symmetry (as opposed to a sixfold symmetry of hexagonal crystals). Although quartz is trigonal by itself, certain crystal shapes make this more obvious. The most common trigonal habit is one where crystals lack z rhombohedral faces. The rhombohedral z-faces generally tend to be smaller than r-faces, and sometimes they are completely absent. Amethyst from geodes in basalt often lacks z-faces. Needle quartz often shows a trigonal habit, too.
