Laser Raman Spectrometer
Laser Raman spectroscopy is a non-destructive testing method that is utilized to study the types of gemstones and the characteristics of mineral inclusions, thereby providing insights into the genesis, origin, and geological environment of gemstone minerals. In Raman spectroscopy, the distinct chemical compositions and structures of various gemstones manifest as unique peak characteristics, which aid in determining the type of gemstone. Raman spectroscopy enables the differentiation between high polymers and organic materials filled within gemstones.
Natural and synthetic gemstones can be distinguished by analyzing the half-width at half-maximum of their characteristic Raman spectral peaks. The sensitivity of Raman spectroscopy reaches the micrometer level, and items with distinct chemical compositions exhibit considerable spectral variability.
Therefore, by comparing the spectral profiles of the elements with those displayed by gemstone jewelry, one can discern the structure and composition of the jewelry.
