Gem materials are an important part of mineralogy due to their beauty and global appeal. Accurate identification is economically vital, and advances in modern testing have transformed gemology from traditional methods to cutting-edge solid-state research. This session focuses on the latest advancements in testing technologies for gemstone materials, including natural, treated and synthetic gemstones. The forum aims to discuss traditional gemological methods as well as modern techniques such as infrared spectroscopy, Raman spectroscopy, UV-Vis spectroscopy, fluorescence spectroscopy, X-ray fluorescence (XRF), laser ablation inductively coupled plasma spectrometry (LA-ICP-MS awa LA-ICP-ToF), scanning electron microscopy (SEM), X-ray Absorption Spectroscopy (XAS) from synchrotron, energy-dispersive spectroscopy (EDS), electron probe microanalysis (EPMA), transmission electron microscopy (TEM), and more recent innovative research methods, such as Atom-Probe Tomography (APT). These technologies offer new perspectives for gemstone detection and enhance our understanding of natural, treated, and synthetic gemstones.We invite contributions that offer new perspectives on the following topics: (1) Technologies and methods of testing natural untreated, treated, and synthetic gemstones; (2) Research on the origin of color and quality evaluation of gemstones; (3) Studies on gemstone inclusions and their significance as indicators of origin and treatment (4) Geological research of gem minerals; (5) Reviews of new testing technologies and their advancements in gemstone identification; (6) Progress in Gem Synthesis Techniques; (7) Other research utilizing modern technologies in the study of gemstone materials.
