Cassiterite on Arsenopyrite (ex Irv Brown Collection)

Item Description

A sharp, well-formed, lustrous Cassiterite crystal measuring 1.0 cm is aesthetically set atop crystallized, silvery Arsenopyrite from this world-famous locality. The Cassiterite might appear to be jet-black, but it actually shows a golden-brown color with a bit of backlighting, which is not common in my experience. A minor amount of tan colored Muscovite makes for a great accent. No damage and incredibly three-dimensional! It's hard to find showy Cassiterite miniatures from Panasqueira, and this piece is a wonderful example of this less common material. From the worldwide thumbnail / miniature collection of Irv Brown.
