The first mass produced face turning octahedron with three cuts per axis although it does not have the octahedrons shape.
At first this puzzle looks like the Concept-11 (aka DaYan Gem III) but the cuts are placed differently. Compared with its predecessor it has no hybrid axis system but implements only (?) the axis system of a face turning octahedron with three cuts per axis.
The puzzle has the shape of a truncated octahedron, an archimedean solid. All puzzles which are named DaYan Gem have similar shapes with fourteen sides.
