Verification of the Authenticity and Classification of Gemstones Using XRF

For thousands of years, pearls, emeralds, rubies and sapphires, as well as other precious gemstones and mineral stones such as alexandrites, aquamarines, etc., have been greatly valued due to their rarity, finite nature and beauty.
