This lovely thumbnail specimen consists of a cluster of Vesuvianite, or(as I prefer calling it) Idocrase crysals that occur in a tetragonal prismatic form with a square cross-section whose corners are truncated by small secondary prism faces. They have rather warped terminations, denoting irregular growing conditions towards the end of their formation. They have a vitreous luster and are translucent due to the fracturing, with small spots of transparence. Like others from this locality, their prism lengths are colored red-violet and their terminations are colored greenish-yellow. They attain a maximum length of 0.8"(2.0 cm), and all that are longer than 0.5"(1.3 cm) seem to have malformed terminations. Most of the crystals are less than 0.2"(5 mm) in length. The specimen is hot-glued onto an acrylic base.
