This Gibeon sphere has almost the exact weight and diameter as used in the Olympic women's shot-put discipline :-).

Pictures 1 and 2 show a small field (center), where the kamacite bars are crossing at 90° = the orientation of the kamacite bars is parallel to a cubic plain. These cubic plains are found 6 times on the sphere.

Pictures 3 and 4 show a small field where the kamacite bars are crossing in 60° = the orientation of the kamacite bars is parallel to a octahedron plain. These octahedron plains are found 8 times on the sphere.

Picture 5 shows the famous drawing from Tschermak (1894) illustrating the orientation of the kamacite bars inside of an iron meteorite.

Roll over, Gibeon. Very nice piece indeed, beautifully presented on the velvet-blue cushion.
