Abstract: There has been few reports and test standards on the high content of hard gold jewelry so far. The process of hard gold jewelry products with the gold content of 999‰ are reviewed in this paper. By means of X-ray fluorescence spectrometry, cupellation method and inductively-coupled plasma atomic emission spectrometry (ICP-AES) were used in order to explore the gold content and the analysis results of three method were compared. It showed that with differernt method the analysis results differed. The method used to test gold content for a certain sample from high to low was X-ray fluorescence spectrometry method, ICP-AES and cupellation. The hard gold jewelry product is different from traditional manufacturing jewelry, so in the actual test process the dection method should be carefully chosen.
