Dozens of tiny Phenakite prisms rest on the crystalline muscovite base of this thumbnail piece. The largest of these crystals is 0.3" (8 mm) long and is the easiest to study- it is in excellent condition and has excellent double-terminated trigonal form. Like the others, it is colorless, transparent, clear, and has a vitreous luster. The muscovite base on which the Joaquinites rest is made up of many well-formed, intersecting platelets.
