Using gemstones' unique characteristics to un
Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones’ past, and with it, historical trade routes. In AIP Advances, Khedr et al. employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. The authors identified elements that influence gems’ color, differentiated stones found within and outside the region, and distinguished natural from synthetic.
