 This simple specimen consists of a single monoclinic prismatic Laumontite crystal.  This crystal is generally in good condition, though I believe that another, partially-intergrown crystal was removed from it.  It has a rather warped form, and appears to be made up of two intergrown crystals by itself.  It has a dingy yellow coloration that is likely caused by a layer of protective lacquer that coats the crystal to prevent it from being dried out.  Its color is actually a rather bright white and its luster is pearly.  One of its prism faces is mostly covered with a crust made up of tiny calcite scalenohedrons, but the rest are clean.  There is no host rock present on the specimen.
