Summary
Worker who visually inspects raw crystal stones for scratches, impurities, transparency, etc., and classifies and sorts them by grade.
Description
Crystal sorters inspect raw crystal stones obtained through mining or procurement using visual checks or magnifying glasses, making detailed judgments on the presence of defects, color tone, transparency, impurities, etc. Based on these judgments, they classify and sort the stones by grade according to product uses or processing steps. The work is primarily manual in factories or workshops, requiring high concentration and accuracy to detect fine scratches or inclusions. In some cases, they may also monitor and maintain automatic sorting machines.
Future Outlook
While automation and mechanization advance, fine quality judgments require manual labor, so demand for sorting high-value products is expected to persist.
