This investigation was undertaken to contribute to the knowledge of sapphire from Kashmir, and over 50 cut stones were studied. Comparison of the observed inclusions with those described in other publications, identified in part using the scanning electron microscope SEM/EDS, confirmed the results of earlier findings (tourmaline, pargasite and zircon inclusions). In addition, some internal characteristics are newly described: plagioclase, uraninite, allanite and rutile (P) occurring in various forms, healed fissures and zoned growth. Spectral properties are presented. The significance of origin reports is discussed.
