Abstract
A gemstone has a faceted crown which is inclined with respect to the main axis and which is defined on the one end by a preferably flat table and on the other hand by a peripheral edge of the gemstone. A faceted pavilion is inclined with respect to the main axis, adjoins the peripheral edge, and converges to a tip. The facets ( ) of the crown ( ) are all inclined at the same crown angle (&bgr;) with respect to the main axis ( ), while the facets ( ′) of the pavilion ( ) are inclined at two different pavilion angles (&agr; , &agr; ) with respect to the main axis ( ). The first set of facets ( ) of the pavilion ( ) which are inclined at a first pavilion angle (&agr; ) extend to the peripheral edge ( ), and the second set of facets ( ′) of the pavilion ( ) which are inclined at a second pavilion angle (&agr; ) start from the tip ( ) without reaching the peripheral edge ( ).
