A druse made up of hundreds of tiny, intergrown Plattnerite crystals coats the limonite host rock of this specimen. These crystals are tiny- most do not exceed 1 mm in diameter- but appear to be in excellent condition and have good tetragonal form. Their black color and bright, adamantine luster are standard for their species. The druse covers almost the entire limonite base and is itself partly covered by a druse of warped and heavily-intergrown calcite blades.
