A classic from Tsumeb mines. It shows a group of very sharp cerussite crystals forming this aesthetic cyclic twinned rosette. Excellent brilliance, good transparency and color from yellow to grayish tones, according to the light striking them. They are aerial disposed on the matrix and accompanied by other small cerussite crystals. It is unusual to get these twins on matrix.

Tsumcorite is a rare lead, zinc and iron arsenate, with Type Locality in Tsumcorp mine (abbreviation of Tsumeb Corporation). This company worked this copper mine during many years, in the Tsumeb mining area. This specimen is very rich in intense orange-brown small crystals of tsumcorite. We can observe platy lanceolated tabular crystals. They are accompanied by mimetite globular aggregates partially covered by brilliant deep green duftite crystals.
