This large, rounded cabinet specimen consists of a chunk of compact, crystalline Actinolite. The crystals that make up the piece are extremely intergrown but still often distinguishable as single units. Though none are intact and complete, their monoclinic form is evident and sometimes well-defined. The Actinolite has a uniform dark green color and a bright pearly luster, and is dimly translucent.
