Mineral Specimen #5178 Yellow and Red Datolite
Lake Superior Copper District, Keweenaw Peninsula, Upper Peninsula, Michigan
Yellow Datolite nodules from the Copper Country of Michigan are very rare and much coveted. This particular specimen is a very large example of one. The color is a dark yellow with plume like incursions of red on the edges with black dendritic centers. The specimen has a high polish. It is likely the specimen is from the Quincy mine (or the Mesnard of Franklin which were both later incorporated into the Quincy). The specimen is from an old collection from the Detroit area.
Flaws: There are three, short, hairline cracks on the polished side.
