This specimen displays a dozen or so green elbaite tourmaline crystals in a matrix of intergrown prismatic colorless quartz crystals. The elbaite has a very dark green color (nearly black in most areas), and is barely translucent. There are enough fractures and surface texture to reveal the green color. The crystals have an unusual distorted diamond shaped cross section, and few of them show terminations, as nearly every crystal is missing one or both ends. They do show typical tourmaline striations and a vitreous luster.
