Rosh Pinah - MAFIADOC.COM

Cerussite, PbCO3, has been periodically collected at Rosh Pinah, although it remains a relatively rare species for the locality. Crystals tend to be small, seldom over 2 cm, with most less than 1 cm; however, the small size is compensated for by their aesthetic twinning, as the cerussite is either highly reticulated or forms V-shaped twins.
