This specimen is one big phosphate specimen! The matrix is a bluish mineral (triphilite? Apatite?). There is a large cavity on the front that is lined with correianevesite crystals and in-turn has a couple of clusters of sharp hureaulite crystals on them. There are also correianevesite crystals formed on and in the hureaulite. Could be other rare goodies in the vug. Excellent specimen!
