This thumbnail specimen consists of a dull, brown base on which rests a single Ludlamite aggregate. The aggregate is in excellent condition, showing no damage, and does not exceed 0.3" (8 mm) in length. It is made up of 3 or 4 intergrown crystals that show excellent monoclinic bladed form. All have the standard grass-green color and pearly luster of their species, and are translucent. A few nearly microscopic pyrite orbs also rest on the base.
