Decorative structure

A gemstone with a chaton cut has tapering facets of a crown adjoin a flat table all the way round inclined relative to the table. The facets extend as far as a rondist at which the gemstone has the largest transverse dimension. A pavilion of facets, preferably terminating at a point, adjoins below the rondist. The gemstone is at least partially made of glass, and the crown angle (&#x3b1;) is between 40.5&#xb0; and 42.5&#xb0;.
