Discrimination of HPHT-treated Type Ⅰa Cape Diamonds Using Optical and Photoluminescence Spectroscopic Techniques
BACKGROUND Spectroscopic characteristics for brown colored Type Ⅱa diamonds treated by high pressure high temperature (HPHT) processes have been investigated extensively. However, almost no reports are available on the variation of the spectroscopic features for the type Ⅰa Cape series brown colored...
