This specimen is almost entirely green heulandite. The largest crystals are on top, and pregressively smaller crystals form the base. Examining the bottom, there is a visible blade of a clear colorless mineral (quartz?) that was the initial structure, and the heulandite crystals attached to it are almost a crust - the individual crystals are very fine. The large heulandite crystals are an excellent lime green color, are dimly translucent, and have a vitreous luster.
