wherein each star set includes one primary star facet and at least two secondary
star facets,
wherein each pair of the upper girdle facet sets includes two primary upper
girdle facets and at least two secondary upper girdle facets,
wherein each bezel facet is nonadjacent from every other bezel facet,
wherein the primary star facets are polygons having 4, 6, or 8 sides,
wherein each primary star facet is positioned between two bezel facets and each
primary star facet is cut approximately 3 or 4 degrees flatter than the adjacent
bezel facets,
wherein each primary upper girdle facet is a quadrilateral polygon,
wherein each primary star facet extends at least 70% from the table toward the
girdle, and
wherein when the gemstone is viewed from above, it appears to have a scalloped
perimeter, and
