Abstract:
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.

Claim (Index 19):
An apparatus for providing a visual or audible indicator as to whether a diamond is natural by measuring luminescence properties of the diamond, the apparatus comprising:\n a source of electromagnetic radiation; a light detection device for capturing visible light emitted by the diamond; and a control system configured:\n to synchronize the source and light detection device; \n to cause the source to irradiate the diamond with an excitation pulse of electromagnetic radiation; and \n to cause the light detection device to capture visible light emitted by the diamond during at least one time window having a predetermined time relationship relative to the excitation pulse so as to obtain luminescence data; \n wherein the or each time window is chosen to encompass one or more specific markers in the luminescence properties of the diamond, said one or more markers characterized by luminescence decay time and luminescence wavelength and providing an indicator of whether the diamond is natural; the apparatus further comprising: a processor configured to provide a visual or audible indicator as to whether the diamond is natural, or whether further analysis is required, based upon the presence or absence of the one or more specific markers.
