MottramiteMottramite

Item number: 19886

An interesting specimen composed of interweaving tubular aggregates of mottramite. I think it has a grey coating of another mineral since it has that colour on the outside and the more normal look of mottramite on the interior of the tubes. Tiny calcite or smithsonite rhombs on the mottramite. EDS confirmed.
