Glistening massive grains of melanotekite throughout matrix. Good example for the species. The specimen comes with a previous label from the collection of Jack Nieburger.

Langban, Sweden, is a renowned historic mining district in Varmland that was worked from the fifteenth century through 1972 for iron and manganese ores hosted within a complex dolomite and skarn environment. Exhibiting extraordinary mineralogical diversity, the deposit formed through ancient submarine hydrothermal activity followed by metasomatic alteration, producing hundreds of unique mineral species. Among these, melanotekite occurs as notable masses associated with native lead and other rare heavy metal phases, making the site a legendary destination for mineral collectors and researchers alike.
