摘　　要：综述了近年来高温高压处理钻石的成果。该处理方法的对象主要有天然钻石、高温高压合成钻石以及化学气相沉淀法合成钻石。系统地总结和分析了该类处理钻石的谱学特征,包括紫外-可见光吸收光谱、红外吸收光谱、拉曼光谱、光致发光光谱及荧光特征,提供了其主要的鉴定依据。The achievements of diamond under high temperature and high pressure （HTHP） treatment in recent years are summarized. The objects of the treatment method include mainly the natural diamonds, HTHP synthetic diamonds and chemical vapor deposition（CVD） synthetic diamonds. The spectroscopic characteristics of these HTHP-treated diamonds are systematically reviewed and analysed, which include that of ultraviolet-visible absorption spectrum, infrared absorption spectrum, Raman spectrum, photoluminescence spectrum and fluorescence, providing the major identification.
