Arfvedsonite

Item Description

A nice specimen consisting of a feldspar rock matrix hosting a lot of undamaged and perfectly terminated jet black arfvedsonite xtals (up to 2 cm) with a great luster. Arfvedsonite is a fairly rare amphibole in nice macroscopic xtals. Also present are smoky quartz xtals and white orthoclase which provide a nice contrast to the black arfvedsonite. There is damage along the periphery as can be seen in the photos but the core is clean and the crystals have SUPERB luster and sharpness for the species. Valued $500-750
