This is a gorgeous cassiterite from an unusual locality - NOT from the more common Viloco mine! It is a jackstraw cluster of very lustrous, elongated, black cassiterite crystals, to 1.5 cm in length. This style is rarely seen. The luster is fabulous! The elongated crystal habit is rare. From the collection of Dr. Art Soregaroli.
