In order to test whether a diamond has had a layer of synthetic diamond deposited thereon, it is irradiated with high energy ultraviolet radiation to cause emission of luminescence, the luminescence intensity produced by different zones of the diamond being measured and compared. In one embodiment an integrating enclosure (15) is used and the diamond (13) is mounted on a rotatable mount (14).

Pour vérifier si une couche de diamant synthétique est déposée sur un diamant, on l'irradie par un rayonnement ultraviolet haute énergie de façon à provoquer une émission luminescente, et à mesurer et comparer l'intensité de luminescence entre les différentes zones. Selon un mode de réalisation, on utilise une enceinte (15) d'intégration, le diamant (13) étant monté sur un support (14) rotatif.
