A bright shiny display surface of Pyrolusite pseudomorphing manganite crystals. This was collected by Glyn Francis in the 1980's and comes with one of his labels. The Iron Prince Quarry closed in 1992 and is now backfilled with tailings from recent mining activity. This area was mined out as ore years ago anyway , so no new specimans will ever come out again. This speciman has better coverage of crystals than most available nowdays.
