JFD200AP4: As those familiar with the deposit know, Panasqueira pyrites can be very good. This piece is a good example of this, with the crystal aggregate forming a very aerial pineapple on a Quartz matrix completely covered by small Calcite-Dolomite crystals and with the mold of another Quartz crystal on the back.
Everything is quite perfect, without any dings, which is not very common in Panasqueira where, due to the operating conditions, it is very difficult to prevent pieces from being damaged.
Luminous and showy, a very good Pyrite.
