CA 2242616

The cut of a gemstone is formed so as to produce between the side edges of each lower facet a group of additional, narrow, triangular facets which fan out from the girdle plane. The narrow surfaces of each additional facet meet, along the lines of connection between the points of the lower facets, with the narrow surfaces of the additional facets of the respective adjacent group. Said cut gives the gemstone a new appearance with respect to brilliance and brightness.

Une pierre précieuse est taillée de manière à créer entre les arêtes latérales de chaque facette inférieure un groupe de facettes additionnelles triangulaires étroites partant en éventail depuis le plan de feuilletis. Les surfaces étroites de chaque face additionnelle rencontrent, le long des lignes de jonction entre les points des facettes inférieures, les surfaces étroites des facettes additionnelles du groupe adjacent respectif. Ainsi taillée, la pierre précieuse revêt un nouvel éclat.
