Jade was one of the most commonly used forms of body ornamentation in prehistoric Southeast Asia. The largest collections of jade artifacts are found in Taiwan, Philippines, and Vietnam, but have also been reported from Thailand, Cambodia, Burma, Malaysia, and Indonesia. The dispersal of jade objects has been studied by generations of archaeologists, primarily based on typology, but more recent studies have utilised geochemical analysis. This allows for a much broader understanding of material source and the more reliable construction of trading networks of jade objects across the region. In the Philippines, at least 20 archaeological sites have yielded jade artifacts in which a large number are identified as green nephrite. However, no green nephrite sources have been reported from the Philippines, nor from other countries in Island Southeast Asia. In this study, archaeological greenstones from the collection of the National Museum of the Philippines were analysed using non-destructive qualitative phase identification with Raman Spectrometer. The aim is to provide preliminary identifications of possible materials used in the manufacture of greenstone ornaments, either when green nephrites were not available, or when people were attempting to make a cheaper product. Thirty-five archaeological greenstone artifacts from Palawan were identified as jade and jade-like minerals. When tested, 23 samples unequivocally correspond to nephrite, 3 were identified as talc, and 9 samples were associated with muscovite. The project demonstrated that Raman spectroscopy is a useful tool in differentiating the different raw materials used in the production of greenstone ornaments. While previous studies had shown that green nephrites are mostly sourced from eastern Taiwan, further geochemical fingerprinting and sourcing studies are recommended to source greenstone minerals available in the Philippines and elsewhere in Southeast Asia.
