The Skewb Diamond has 6 octahedral corner pieces and 8 triangular face centers. All pieces can move relative to each other. It is a deep-cut puzzle: its planes of rotation bisect it. It is very closely related to the Skewb, and shares the same piece count and mechanism. However, the triangular "corners" present on the Skewb have no visible orientation on the Skewb Diamond, and the square "centers" gain a visible orientation on the Skewb Diamond. Combining pieces from the two can either give you an unsolvable cuboctahedron or a compound of cube and octahedron with visible orientation on all pieces.
