SOLD
An very FINE, large, sliced and polished datolite nodule half from Michigan's Copper Country. This white beauty is porcelaneous and has an unusual pastel-green core with dentritic, red highlights on the edges (caused by copper, I presume). This showy piece is from Isle Royal in Lake Superior, where not too many datolite nodules have been recovered. Ex. Seaman Museum Collection.
