Abstract
A portable neodymium magnet is one of the most useful and least-known tools for identifying gems. The results of the work demonstrate the possibilities of using this tool in conducting field gemmological studies, as well as directly in the retail jewelry trade.
Keywords: neodymium magnet, gemstones, diagnostics, magnetic susceptibility, paramagnetism, diamagnetism.
