- The Moravian star is generally a 26-point form, composed of eighteen square and eight triangular cone shaped points. This shape is technically known as a Great Stellated Rhombicuboctahedron. Each face of the geometric solid in the middle, the Rhombicuboctahedron, serves as the base for the "stellations" or starburst points. The Moravian star is a popular illuminated piece of Advent or Christmas decoration but was most likely first developed as a geometry lesson at a Moravian Boy's School in Germany.
