Native iron mineral - You can buy these samples

Native iron is a mineral belonging to the group of native elements. This mineral can have both terrestrial and cosmogenic origin. A distinctive feature of terrestrial origin from cosmogenic is the nickel content increased by 3% in terrestrial iron.

You can see native iron stone for sale and buy it in the Minerals of Russia online store.
