Vivianite pseudomorph after Belemnite Fossil

Item Description

Rare but interesting and beautiful material from the oddball Mullica HIll phosphate locality in southern New Jersey (about 25 miles south of Philadelphia). Mullica Hill is best known for its phosphate species (it's actually the type locality for Ferrostunzite), especially the attractive pseudmorphs / replacements of Vivianite after marine animals. This piece features dark greenish-black crystals of Vivianite in an oddly tubular formation which have replaced a Belemnite fossil. The crystals are quite sharp and lustrous for the locality, as they can often be dull and rounded. Very cool material, and not what one expects when it comes to minerals from New Jersey.
