This small thumbnail specimen consists of a flat, pyritic base on which rest at least 10 Ludlamites. These crystals are quite small, not exceeding 0.1" (3 mm) in length, and are generally in very good condition. All have excellent monoclinic prismatic form that is relatively easy to study with a loupe, and their dull, grass-green color and pearly luster are standard for the specie. They are also transparent and moderately clear. I think that these are some of the best-formed Ludlamites that we have had yet.
