Shanghai Jewelry Testing and Appraisal Office has new recruits in the new year
Just in 2009, many jewelry testing and appraisal offices in Shanghai began to use a new gemstone detection method: reflectance color detection. This is a method to distinguish the true and false gemstones from the advantages and disadvantages of gemstones based on the phenomenon that different gemstones have different reflectances in different wavebands. Because of its simple device, small and handy, it has strong qualitative ability. Therefore, it has been favored by many institutions in Shanghai.
The micro fiber spectrometer system operated by our company is a typical representative of this emerging detection method. It is an instrument that can measure reflectivity and measure color. The so-called measurement is to detect the true and false colors of gemstones, such as colored pearls, colored diamonds, and gold beads that are currently popular in the market. The true and false colors can only be judged by the reflection color measurement of the spectrometer. The so-called measurement means that the instrument can be used to measure the spatial value and reflectance distribution data of the color, and the color can be accurately expressed by the numerical value. These data are the important basis for the later jadeite classification and pearl classification. At present, many appraisal agencies in Shanghai have purchased our products.
