Native iron is extremely rare in igneous rocks, even though it forms the majority of the Earth's core. This old-time specimen is from remote Disko Island, Greenland and is a nodule richly speckled with bright, metallic, rust-brown native iron. The native iron formed as nodules in basalt. This specimen dates to the late 1800s and comes with an old, faded, printed label. The collection this came out of was a museum stash dating to prior to World War I.
