Arfvedsonite, Quartz (Var: Smoky Quartz), Orthoclase
Mt Malosa, Zomba District, Malawi
Cabinet, 12.5 x 9.4 x 6.0 cm
A nice specimen consisting of a feldspar rock matrix hosting a lot of undamaged and perfectly terminated jet black arfvedsonite crystals (up to 2 cm) with a great luster. Arfvedsonite is a fairly rare amphibole in nice macroscopic crystals. Also present are smoky quartz crystals and white orthoclase which provide a nice contrast to the black arfvedsonite.
