enantiomorphism
Having crystal forms that, while possessing neither a plane nor a center of symmetry, may occur in two positions that are mirror images of one another. The two positions cannot be converted into each other by any rotation, but are related to each other as are the right and left hand, hence designated right- and left-handed forms. Enantiomorphous crystals cause circular polarization of light, e.g., quartz.
