Item Description

An impressive large combination specimen from this renowned locale. Two generations of sharp, moderately lustrous, light brown siderite disks, to 3.0 cm on the diagonal, richly cover the hefty ore matrix of parallel-growth, striated, lustrous, jet-black ferberite blades. The many siderites on both sides of this showy piece are nearly pristine, with only a couple of bruised crystals. A few of the ferberites are terminated, with most being contacted. This remains a showy and highly representative example of the combination species from this famous locale. Valued by the former dealer at $550.
