Examples: Rhombohedral twinning in corundum, quartz (amethyst) and calcite. Within corundum, polysynthetic twinning occurs parallel to the faces of the rhombohedron {1011}, which intersect each other at angles of 86.1 and 93.9° and meet the c axis at 32.4/57.6°. Repeated twinning in corundum is easily observed under the microscope.
