Gem

 XRF is also widely used in gemology and gemstone identification, contributing to research and applications in gemstone identification, origin analysis, and gemstone studies. Different types of gemstones have different elemental compositions, so by analyzing the elemental characteristics of a gemstone, it is possible to determine whether it is natural, synthetic, or imitation. The elemental content of a gemstone can be related to its origin. The origin of some gemstones can be determined by examining their elemental compositions, making XRF analysis helpful in identifying the possible source of a gemstone.
