Several shreds of Palygorskite are partly embedded in the crystalline calcite of this specimen. These shreds are made up of countless superfine Palygorskite fibers that have been matted into a "fabric" of sorts. It has a pure white coloration and an almost silky luster and is quite flexible where loose. The surrounding calcites have an excellent tabular "nailhead" form and are rather heavily intergrown. They are colorless and dimly transparent and show a pearly luster.
