This specimen consists of hundreds of tiny intergrown orthorhombic prisms of bertrandite. There is no matrix material with this specimen. Some of the bertrandite crystals are transparent, showing striations and vitreous luster. Near the base of this specimen is one crystal of bertrandite showing a hexagonal shape. I believe that this is a pseudomorph of bertrandite after beryl.
