A very rich and fine specimen of the rare phosphate Tarbuttite from the Kabwe Mine (Broken Hill Mine), Zambia - the type location. Excellently formed bladed crystals of Tarbuttite measuring to around 4-5mm are densely intergrown over a dark brown Goethite gossan with micro-crystal of white Pyromorphite. The specimen comes with an old Anton Berger label.
