OSC24 Scorodite

$375
A nice example hosting several large and well formed scorodite crystals, some with surface etching. They appear black, though on a couple of the crystals small enough for light to pass through, you can see a bit of blue. There is some damage, though this remains a good and very rich example for the price.
