VIVIANITE

Group of vivianite intergrowth crystals, with a prismatic shape showing pinacoidal faces. Very deep green color, good transparence and brilliance. We believe that the absence of sulphides in the rocky matrix will preserve the chemical stability of these specimens. THE MAIN CRYSTAL IS: 4,5 x 2,4 x 1,5 cm.
