Title (EN) LUMINESCENCE MEASUREMENTS IN DIAMOND
(FR) MESURES DE LUMINESCENCE DANS LE DIAMANT
Abstract:
(EN) A method of and an apparatus for providing an indicator for a diamond as to whether it is natural by testing for the presence or absence of one or more specific markers in the luminescence properties of the diamond, These markers are characterised by luminescence decay time and luminescence wavelength.
(FR) L'invention concerne un procédé et un appareil pour la fourniture d'un indicateur pour un diamant quant à savoir s'il est naturel par la vérification de la présence ou de l'absence d'un ou de plusieurs marqueurs spécifiques dans les propriétés de luminescence du diamant. Ces marqueurs sont caractérisés par une temps de décroissance de la luminescence et une longueur d'onde de luminescence.
