Description

Groups of pyromorphite crystals (analyzed) which are disposed on a matrix of goethite. The green yellowish color is very intense, exceptional brilliance, translucent to transparent. They show defined hexagonal prisms truncated by the pinacoid. Under magnifying glass transparency we can be seen perfectly. They come from a Moroccan locality that once was known by the presence of pyromorphite, but not with this quality and less represented in collections.
