Verdelite (Tourmaline)
Verdelite is a green variety of the tourmaline group. The name verdelite is not a valid mineral species approved by the International Mineralogical Association (IMA). The name is derived from the Italian word verde (green) and the Greek lithos (stone). It forms typical prismatic crystals, i.e., columns elongated along the longitudinal c-axis, the cross-section of which is a typically rounded triangle. Distinct vertical striations parallel to the c-axis are also characteristic. The green coloration is the result of the presence of divalent iron, trivalent chromium, and vanadium. Verdelites are primarily bound to lithium pegmatites and sporadically also to metamorphic schists.
