Långban, Filipstad, Värmland County, Sweden
Size Range: 
Miniature (4.5-7 cm)
Size: 
5.3 × 5 × 2.6 cm
Description

Massive native lead specimen from langban, partially altered to white hydrocerussite. One features brown to black crystals, which might be pyrochroite. What appears strange after EDS analysing them, is in my mind the Pb. This could either be from matrix as impurity or it is another species, although this mineral assemblage is quite typical
