A specimen of well distributed, sharply crystallised pseudo-hexagonal crystals of Tarnowitzite to 13mm. The crystals are opaque white through to transparent colourless and appear to be more opaque in the prism terminations and clearer in the midriffs - their lustre can described as vitreous. The crystals are undamaged though one crystal on the periphery has a point of detachment. A tidy and neat example of this rare lead rich Aragonite variety.
