Large Berthierite on Siderite (old rare style) ex Paterson Mus. Coll.

Item Description

An impressive, large, rare style berthierite combination specimen from the famous Herja Mine. Iridescent needles of berthierite, Fe-Sb sulfosalt, are dramatically emplaced in parallel-growth on both sides of the fantastic large bladed cluster of intergrown knobby plates of sparkly siderite rhombs. Rare, perhaps unique large combination material from this noted locale. Old-time, circa early 1900s material from the Paterson Museum Collection, but with no label. Value of such an unusual large old-time piece??
