Mesnard Mine (Quincy No. 8 shaft), Quincy Mine, Hancock, Houghton Co., Michigan, USA 7.2 x 6.4 x 2.8 cm. A showy and excellent, slabbed and polished red datolite nodule nicely set in matrix from the Mesnard Mine of Michigan. The datolite has a nice porcelaneous look and the red color is the result of copper inclusions. Red datolite nodules from Copper Country are always in demand. Ex. Dean Martalock and Seaman Museum Collections. |
