Abstract

Gemme composite (100) comprenant : - un corps principal (10) en diamant ayant une face ; - une structure de coloration (13) de ladite face par interférence optique, comprenant une couche enterrée (12) semi-transparente ou opaque, d’indice de réfraction n1, disposée sur la face du corps principal, et une couche de revêtement (11) en diamant, d’indice de réfraction n2, recouvrant complétement la couche enterrée, ; la différence entre n1 et n2, en valeur absolue, étant supérieure ou égale à 0,1 ; la couche enterrée étant apte à réfléchir un faisceau incident de lumière visible réfracté (22) par la couche de revêtement et la couche de revêtement étant apte à fournir une coloration par interférence entre un faisceau incident de lumière visible réfléchi (21) par une surface externe de la couche de revêtement et un faisceau (24) réfracté par la couche de revêtement après réflexion sur la couche enterrée. Figure pour l’abrégé : figure 3A composite gem (100) comprising: - a main body (10) of diamond having one face; - a coloring structure (13) of said face by optical interference, comprising a buried layer (12) semi-transparent or opaque, of refractive index n1, arranged on the face of the main body, and a coating layer (11 ) diamond, refractive index n2, completely covering the buried layer,; the difference between n1 and n2, in absolute value, being greater than or equal to 0.1; the buried layer being adapted to reflect an incident beam of visible light refracted (22) by the coating layer and the coating layer being adapted to provide coloring by interference between an incident beam of visible light reflected (21) by an outer surface of the coating layer and a beam (24) refracted by the coating layer after reflection on the buried layer.
