This meteorite was found around 1950 near Zaragoza and sold to a mineral collector. Years later, his widow at a mineral fair sold it to Americans Jim Strope and Michael Farmer who cut it into slices and small pieces to sell it to other meteorite collectors. According to him, it has been the hardest meteorite that he has ever cut, since he needed around 3 full days to cut each slice. It weighed 162kg and only one piece is known. This had regmaglyphs on a surface that was worn and had some cracks. Zaragoza is an anomalous type IVA metallic meteorite, given its high germanium content. It is an extremely hard and stable meteorite, with a smooth pattern that can only be seen up close.
