In the modern gem trade, the provenance of a stone—whether it originated in the mines of Colombia, the pegmatites of Madagascar, or the gravels of Myanmar—can significantly impact its value. While chemical analysis can determine origin, it is often destructive or requires expensive laboratory equipment. Inclusions, however, offer a non-destructive window into the stone’s genesis. The Photoatlas provides high-resolution color micrographs of characteristic inclusions from specific localities. For instance, the presence of "horsetail" inclusions of byssolite is a hallmark of demantoid garnet from Russia, while jagged, three-phase inclusions are indicative of emeralds from Colombia.
