A great ore specimen showing the arborecent crystallization of Safflorite in 1cm rods suspended in hard Calcite matrix. At the tips of the Safflorite is the remaining phase of Nickeline marking the depletion of cobalt. On the flip side you can see the alterations to probably Annabergite. It is a slice on one side. You will have endless hours of studying the ore development under the microscope.
