Item #17826 Cerussite, Malachite 9.5x5.2x2.1 cm Largest Crystal Size: 3mm $55.00 Tsumeb Mine Tsumeb Namibia At first glance this specimen looks like a thin pate that has many, deep green tufts of acicular malachite over much of its surface. On one side, amongst the malachite crystals are lovely, well-formed white cerussite twins. They are not big but the malachite is colourful and a nice contrast to the white cerussite. Lots to look at!	Item #17150 Malachite 10.5x6.2x4.2 cm Largest Crystal Size: 5mm $85.00 Tsumeb Namibia The top of this matrix, which seams to be breccia cemented with carbonates and malachite, is coated with radiating deep green, acicular malachite crystals. Some areas of the acicular crystals have been sheared off but for the most part, all of the terminations are intact! Displays very well!	Item #17167 Malachite 12.3x9.5x5.5 cm Largest Crystal Size: 4mm $60.00 Tsumeb Namibia The top of this malachite-limonite-chalcocite matrix is covered with a druse of rounded aggregates of acicular malachite. The piece is significantly abraded but still looks great and should travel fairly well. Classic high grade ore!

Here is a nice example!
