Outstanding large group of twinned cubic uraninite crystals (much much better in person, pardon my photos!!) from a classic Canadian locality near Bancroft. One of the best I have seen from this locality, both in size and crystal development. Very HOT- Measures ~180,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Rare!
