Dark Red Datolite Nodule
Dark Red Datolite Nodule from Knowlton Mine, Mass City, Ontonagon Co., Michigan
Collection Robert Lavinsky
Description The Datolites from Michigan come in such a range of subtly pretty colors that the variety of specimens is endless, due to the numerous types of inclusions that give them their hues; so many people have a collection of Datolites as a special sub-section of their collections. Unfortunately, they are not common. This is a big one, with a gorgeous rusty-red center (probably from Hematite) - highly polished to bring out the beauty. If you look closely, you can see little inclusions of native Copper around the rim.
Locality Knowlton Mine, Mass City, Ontonagon Co., Michigan
Dimensions 8.9 x 7.9 x 3.4 cm.
Specimen Grade C
