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!

Some areas of the acicular crystals have been sheared off but for the most part, all of the terminations are intact! Displays very well!
