This small thumbnail specimen consists of a single trigonal prismatic Elbaite tourmaline crystal. The crystal is in very good condition, though it does show a tiny spot of damage at its highest point, and has incomplete but reasonably good form. Its color is a moderately pale green-blue and its luster is vitreous. Though it is transparent, the crystal is also very heavily internally-fractured and has very little clarity. It is partly covered with many tiny intergrown lepidolite "books" that do not exceed 0.1" (3 mm) in diameter and are moderately well-formed. There is no host rock present.
