Calcite ps. Ilvaite (Ref: P266)

Dal'Negorsk, Russia
32mm x 32mm x 25mm
$600
Rare pseudomorph specimen featuring a cluster of 3 crystals of Ilvaite that have been replaced by grey Calcite. These are seldom seen and even among those I've seen, this one displays with dramatic flare with all 3 crystals spraying outward. Small Pyrite crystals are present on the surface. Complete all around and undamaged classic Dal'Negorsk pseudomorph. Ex. Carl Acosta collection.
