Vivianite on fossilized mollusc (large) Soregaroli Coll.

Item Description

A rare, excellent and large specimen from the Kerch Peninsula. The interior of the fossilized mollusc shell is covered with a crust of vivianite and striking sprays of lustrous, variably-sized vivianite blades. Some the blades have gemmy sections and colors range from black to olive-green. The matrix is a dense shell hash. This phosphate pod deposit is now mined through and gone. It is extremely rare to obtain specimens today of this top quality. Ex Art Soregaroli Collection.
