WebTopaz. 1. Parting (pseudo cleavage) – Some crystals can be divided in two, along a plane of weakness known as a parting plane which is along a twin plane. Parting is usually due to lamellar twinning, as in labradorite feldspar. Parting is possible only along definite planes in twinned crystals and not along every parallel plane.
