Orthoclase ("Carlsbad" Twin) (ex Josef Vajdak)

Item Description

A classic specimen of the famous but hard to find twinned Orthoclase Feldspar crystals from the locality at Loket in Bohemia. This piece is a complete "floater" featuring a sharp, well-formed, beige colored "Carlsbad" twin of Orthoclase. There has been some debate as to whether or not Loket is the type locality for the "Carlsbad" twin habit for feldspar, since "Karlsbad" / "Carlsbad" is the old name for Karlovy Vary, which is the namesake for the twinning habit.
