Which gems can the infrared spectrometer identify?
The use of infrared spectroscopy to detect gemstone samples is currently based on experimental data and is therefore semi-empirical. Nevertheless, infrared spectroscopy has greatly compensated for the shortcomings of conventional testing instruments, and has become a new non-destructive identification method for research and detection of jade, and its application range mainly has two aspects.
1. Distinguish between natural and synthetic gemstones. Despite the various inclusions contained within the gemstone, gemologists can distinguish natural gemstones from synthetic gemstones. However, for some gemstones that have little internal flaws or contain inconsistencies, conventional gemstone testing instruments are often at a loss. In contrast, infrared spectroscopy provides fast, accurate, and damage-free test results in a matter of minutes.
By means of infrared spectroscopy, it is possible to: 1 separate the emerald green and the synthetic emerald; 2 to distinguish the natural gold emerald with the intrinsic lack of characteristic inclusions from the synthetic gold emerald; 3 to distinguish the natural amethyst from the synthetic amethyst.
2. Detect some gemstones that have been manually optimized. For gemstone materials, such as opal, turquoise, jade, crystal, etc., which are impregnated or filled with polymer materials such as plastics, epoxy resins and silicon-based polymers, infrared spectroscopy is also unique.
