Hopeite - modern classic
Broken Hill (Kabwe Mine) Kabwe District
9.6 x 5.4 x 5.1 CM (cabinet)
A very large, well-crystalized specimen of this rare hydrous Zinc Phosphate. All sides of this specimen are encrusted with rust-red color orthorhombic crystals, most of which have distinct form and are coated with a sparkling druse of tiny crystals that seem to be a second generation of transparent colorless Hopeite. This locality had produced the very best of this specie most of which were found when Zambia was still called Rhodesia. No new finds are reported, these classic specimens are only available from older collections.
An open cavity fully lined with sharp, clear Tarbuttite crystals and with close exam some white acicular Scholzite crystals. Tarbuttite is quite rare worldwide but from two localities it was found at one time in good amounts and in high quality. The old Broken Hill (Zambia) and the Skorpion Mine in Namibia have both produced some well-crystallized and attractive specimens. These locales had a completely different look. This Broken Hill (Kabwe Mine) piece has lustrous, gemmy clear and very sharp crystals that are in fine condition overall and contrast with the matrix well. Choice and displays very well.
Tarbuttite and Pyromorphite
Kabwe Mine (Broken Hill Mine) Kabwe
6.5 x 3.1 x 2.4 CM (cabinet)
Two habits of Tarbuttite crystals are contrasted by distinctive green Pyromorphites. An unusual combination of species, I have not seen these together before. The Tarbuttite is very sharp and in distinct crystals, the Pyromorphite has the unusual habit of pointed pinacoid terminations (many are doubly terminated) and are color zoned with a transparent area in the center. This locality (Kabwe) was known as the Broken Hill mine of Northern Rhodesia, from 1906 until 1964. This is an older specimen.
