Vivianite on fossilized mollusc (Trimingham Coll.)

Item Description

A rare and excellent specimen from the Kerch Peninsula. 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 neon-blue to neon-green. This phosphate pod deposit is now mined through and gone. It is extremely rare to obtain specimens today of this top quality. Ex Bob Trimingham Collection and formerly from the Fersman Museum, according to his label.
