Abstract
A gemstone has a chaton cut, in which a crown adjoins a flat table and has facets that are inclined downwardly relative to the table all the way round, wherein the crown has main facets that extend substantially from the table as far as a girdle at which the gemstone has the largest transverse dimension. A pavilion of facets, preferably facets converging to a point, adjoins below the girdle. The gemstone consists preferably entirely of topaz, and the angle of the main facets relative to a cross-sectional face arranged parallel to the table is between 32.5° and 34.5°.
