Description: Orthoclase is one of the most common minerals and is found worldwide. The original Carlsbad twins were described from Karlovy Vary (Carlsbad), Bohemia, Czech Republic. This specimen is an excellent, well-formed cluster of Carlsbad-twinned Orthoclase crystals. The crystals are sharp, pearlescent gray. The Carlsbad twin is a penetrating twin, in which the twinning axis is the c axis, the operation is a rotation of 180 degrees, and the contact surface is parallel to the side pinacoid. It is quite common in the alkali feldspars. An alternative spelling is Karlsbad twin.
