AEGIRINE with Quartz / Orthoclase / Zircon (Sodium-Iron Silicate) from Mount Malosa, Zomba District, Malawi. Black aegirine crystals protrude from a base of white orthoclase feldspar. Smoky quartz crystals have grown to the right, from the base of the aegirine. Reddish zircons are studded throughout, but too small to see in this photo. A hand sized specimen with beautifully terminated crystals.
