Malachite on Calcite (Onganja, Namibia)
Onganja Mine, Namibia. 70mm x 70mm x 50mm.
Deep green tufts of Malachite rest on the tan coulered calcites. There is evidence of contacts on the sides where the specimen was broken out of the matrix however given this specimen had to have come out in the mid 1970's it is still in remarcable condition.
