| Abstract |
Thailand has the export value of gems and jewelry as the third most important export product of Thailand's total exports. The production of counterfeit jewelry was distributed to many markets to meet the market. Create problems for investigation and investigation of officials. The research aim, to investigate the difference between fake jewelry and genuine jewelry types with Scanning electron microscope (SEM) and Fourier Transform Infrared Spectrophotometer (FTIR). In the trial 12 samples of genuine jewelry and fake jewelery type Jade, Sapphire and Ruby tested by Scanning electron microscope (SEM) with the Energy Dispersive X-Ray Spectrometer, fake jewelry and genuine jewelry the appearance of the surface and trace elements are distintly different. Samples of jewelry and fake jewelry were analyzed with a Fourier Transform Infrared Spectrophotometer (FTIR) at 4000-600 cm-1, the spectra of fake jewelry and genuine jewelry made of all samples were different and some sample were similar. Due to some elements, the substance in both jewelry samples partly similar. However, peaks can indicate the composition of jewelry.This study found analysis of jewelry with Scanning electron microscope (SEM) with Energy Dispersive X-Ray Spectrometer can be used to distinguish between genuine and fake jewelry. The method is easy, easy to analyze. It also provides accurate and accurate analytical results can applied in forensic science.
