Abstract
In this study we examined 45 synthetic diamonds from a gemological point of view to find difference from natural stones. These diamonds were melee-size grown by HPHT method in the range between colorless to near-colorless. All the samples were round brilliant-cut loose stones weighing between 0.0075 and 0.023 ct which were produced in China. These stone can be identified by PL spectroscopy and UV luminescence image.
