Crystal Classics - Weekly Update
14th September 2018
This weeks update features a vibrant selection of specimens from the famous Tsumeb Mine:
- Very fine acicular, hair-like crystals of the very rare molybdate Biehlite radiate out as individual silky needles to about 1cm and also form compacted tangled mats which act as the matrix
- Beautiful microcrystalline Duftite forms a layered, crab-like shell in shades of earthy lime-green to dark leaf-green. This highly unusual cast has formed in curved, curtain-like stacked shells of Duftite with no attached matrix. Superb!
- Bright blue crystalline Linarite dominates the display surface of a brecciated, pale greenish-yellow matrix. Surrounding this are other areas of Linarite, granular blue-green Caledonite, green Malachite and colourless to light grey granular Cerussite
- Shell-like casts of creamy Dolomite are draped over bundles of pale creamy-yellow Aragonite crystals of the lead-rich variety, Tarnowitzite. A very aesthetic specimen which clearly shows the paragenesis between the crystalline Aragonite core and the overlying Dolomite casts
- A very rare and choice specimen of the zinc arsenate hydroxide Paradamite, as terminated lustrous acid-lemon-yellow crystals on a dark fragment of Dolomitic matrix. The specimen is accompanied with a label noting analysis by Raman spectroscopy
- A curious, little finger-sized (and shaped) stalactite of highly lustrous pale lilac Dolomite speckled with dark-green spheres of Mottramite to almost 1mm diameter. The glassy Dolomite crystals form an outer skin to the Calcite core of this most attractive and unusual specimen
