Apophyllite
Castle Danger, Minnesota, USA
The apophyllites are about 2 cm
These are part of a large (40 cm) rock (coarsely crystallized gabbro) found last weekend on the coast of Lake Superior that split perfectly down the middle revealing a number of pockets. Now for some extensive work with the rock trimmer to turn these into specimens. (Author: John Nash)
