Prismatic crystals, also laths and grains.


Classification of Parapierrotite

Approved
2.HC.05f

2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
H : Sulfosalts of SnS archetype
C : With only Pb
3.8.14.1

3 : SULFOSALTS
8 : 1 < ø < 2

Black
Hardness (Mohs):
2½ - 3
