Exceptional specimen of rare nickel sulfides showing the arborescent growth of several minerals overgrowing the next. I cannot tell which is which. There is also Bismuth in the mix. Remarkably similar to Cobalt, Ontario, Canada. The backside is rough.

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.

Truly an amazing specimen with interesting ore genesis and great for ore microscopy. The face is sawed flat. The flip side is natural and rough.
