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.
