This interesting older Broken Hill specimen comes with an old label from Georg Jasker in Hamburg, suggesting that it pre-dates the 1960s. It is certainly not so much a display specimen, rather a classic rarity. Forming a dense aggregate of white to cream-coloured Cerussite, this lead carbonate matrix is partially coated with pale green Malachite along with several small, but well-defined cream-coloured waxy crystals of Chlorargyrite, but the bromine- and iodine-bearing variety. This silver-bearing species is well-known from Broken Hill mine, but these crystals, despite being small are recorded on the label for their complexity - as "kub-hexakisokt" which is probably cubo hexakisoctahedra. There is also a little Massicot mentioned on the old label too, which is probably the small areas of red. A fascinating old rarity from Broken Hill.
