Abstract
In this article, the spectroscopic methods used to assess gem-quality diamonds are reviewed. From such measurements it is possible to determine, in the majority of cases, whether the colour of a stone is natural, or has been changed by some form of treatment-either HPHT processing, radiation damage and annealing, or a combination of both methods. Methods used to identify synthetic diamonds are also covered briefly. (C) 2003 Elsevier B.V. All rights reserved.
