Update: 30 September, 2023
A new technique for the analysis of corundum that has undergone heat treatment and beryllium diffusion to resemble one of the most valuable colored stones: vivid orange-yellow gems known as padparadscha is developed in this study. The technique is based on laser-induced breakdown spectroscopy (LIBS), and chemical analysis with inductively coupled plasma-mass spectrometry (ICP-MS) is used to verify the LIBS data. The method can be used to distinguish natural and treated gems, especially in the case of unknown treatments. This study shows that the method can be used to determine the authenticity of gems.
