- Apophyllite-(Kf), Graphite
- French Creek Mines, St. Peters, Warwick Township, Chester Co., Pennsylvania, USA
- Cabinet, 9.9 x 9.7 x 8.5 cm
A big, rich example of a now quite-rare old-timer from this classic American iron mine! This 3-dimensional "sheety" specimen is COVERED with sparkly crystals of apophyllite. It is an interesting association piece, too: here and there are small blebs of graphite. This piece was sitting in a collection for many decades.
