Earrings with stellated octahedra—geometric bodies that constitute the union of two centrally symmetric tetrahedra Earrings with stellated octahedra—geometric bodies that constitute the union of two centrally symmetric tetrahedra (one of paper-thin 18K white gold, and another of 22K yellow gold). Both octahedra are identical—the inverted color schemer esults from a rotation of the tip of either the white or the yellow gold tetrahedron to the top. A special quality of a stellated tetrahedron is that if placed within a cube, each of its eight tips will touch exactly one of the cube’s eight corners.
