A great speciality of Tsumeb is on offer here. It is a pseudomorph of strong green Bayldonite crystals after columnar Mimetesite. Bayldonite completely replaces the mimetesite. Included are two collection labels as shown (the historic label is a copy of the original). Very interesting and rarely seen pseudomorph of classic deposit. The specimen is in the old original glass tube (size 4x1x1 cm).
