This specimen of Tarnowitzite is from an Old Collection which was collected between the 1980's to early 2000's.
Traditionally called 'tarnowitzite', much 'tarnowitzite' has been identified as a mixture of aragonite and cerussite, but lead-bearing aragonite with up to 3% PbCO3 may be homogeneous.
Variety of Aragonite.
Pearly, opaque, intergrown, subtle yellow to white crystals.
Clear, intergrown, pearly rhombohedral Calcite crystals have developed on the matrix.
Minor green Duftite can be seen on the perimeter of the specimen too.
