Well crystallized Pyrite is not too common at Panasqueira, less so in groups of such well defined cubic crystals as in this piece, in which they are partially covered by very aerial parallel growths of lenticular crystals of white Dolomite.
Minas da Panasqueira, Level 2, Beira Baixa, Portugal.
Found in 1992
Specimen size: 4.6 × 4.4 × 2.2 cm
