This specimen consists entirely of a crust of compact, crystalline Collinsite. A few hollows in the crust hold clusters of Collinsite needles that reach 0.2-0.3" (5-8 mm) in length and are generally in good condition. All have good triclinic form and a pearly luster. All of the Collinsite has a more or less uniform pale green color, though the actual exposed crystals are pale and somewhat grayer in color. Apart from thin brown skins on either side of the crust, there is no host rock present.
