This is an old, classic, Tsumeb double pseudomorph with large crystals of rosasite after malachite, after azurite. The largest tabular rosasite crystal is 4.5 cm in length and exhibits a matte luster along with a slight forest green color. Minor smithsonite and cerussite make up the matrix. This specimen carries an old Bosch label and is a wonderful example of the treasures from early Tsumeb days.
