A naturally etched plate of white Calcite matrix is smothered across its top surface with pearlescent Roman sword blades of translucent, silvery-grey Stilbite (probably Stilbite-Ca) to 6 mm long. A rich specimen and good example of this zeolite group mineral from the St. Andreasberg mining district in the Harz Mountains, Lower Saxony.
