Epistilbite, Chlorite

Premia, Verbano-Cusio-Ossola Province, Piedmont, Italy

9×6,5×3 cm. (main crystal about 2,7×1,4×1 cm.)

Extraordinary single crystal of Epistilbite aesthetically towering on a gneiss matrix and curved elong its growth axis. Normally Epistilbite color is white, but in this case the external crystallized layer is densely colonized by Chlorite for a final catch eyes metallic luster effect; it’s grey in color with some pale green highlights; in evidence, on one side, a brilliant surface characterized by many microcrystals of Chlorite. In conclusion a rare and wonderful specimen from this classic italian locale.
