Jamesonite is a sulfosalt mineral with formula Pb4FeSb6S14.
It comes from Pitangui, Belo Horizonte, Minas Gerais, Brazil.
It is found in the sames quartz crystals that produce Ankangite and Celsian inclusions. Jamesonite paragenesis is younger than ankangite-celsian because it grows in a higher portion of the quartz crystals, indicating lower temperature.
Some Jamesonite crystals appear to be partially or totally replaced by yet undetermined Sb white-yellow alteration minerals, that can be Valentinite or Cervantite.
Associated with jamesonite have been found also small, clear, tabular crystals of Fluorapatite and the very rare mineral Cebaite (Ba3Ce2(CO3)5F2). It is not certain if they are present in this piece.
Hard to find piece for high level collector.
