The definition of Boulangerite is given as a lead , antimony sulphide that often forms feathery masses also refered to as plumosite. This specimen has a good nest of them on the side, we where focussing on the pyrite when taking the pictures hence the earlier statement.
It's a rarity and something we where really surprised to find within the collection. Packed shipping weight will be +/- 150gr.
