Brazil twin
A type of twin found in quartz in which the two crystalline individuals are of opposite kinds, one being right-handed, the other left-handed, with a face of the trigonal prism of the second order as twinning plane. Since one is not derivable from the other by any rotation, there is no twinning axis.
