A crust made up of scores of small, white Edingtonite crystals coats the crystalline calcite host rock of this specimen. The Edingtonite crystals are in very good condition, with damage mostly limited to the crystals along the crust's edge. They do not exceed 0.2" (5 mm) in length and their tetragonal prismatic form is well-defined. They have a white color and a pearly luster, and range from translucent to nearly transparent. The calcite that acts as their base is in the form of a few intergrown rhombohedral crystals that show considerable damage. Some of the calcite has a brighter color than most of it, and almost appears to be striated, but it is definitely calcite, and has probably taken on the tendencies of a mineral that was adjacent to it.
