Figures of the Article

• Kashmir sapphire sample SK1 (a-d), sample SK2 (e-f) and faceted blue sapphire sample SKG1 from Kashmir (g-h)
• Cathodoluminescence images of zircon inclusions in the sample SK1
• Cathodoluminescence images of zircon inclusions in the sample SK1-z14: Measuring spots 14-1 to 14-5
• Conventional U-Pb Concordia plot showing SIMS analytical data of zircon inclusions in Kashmir sapphire sample SK1. The red ellipsoids each represent one measurement from a single zircon, and the blue ellipsoid gives the resulting weighted mean concordant age and error from the zircons within the sapphire sample SK1
• U-Pb Concordia plot of LA-ICP-MS analytical data of zircon inclusions in Kashmir sapphire sample SK2. One measuring spot was car-ried out.
• U-Pb Concordia plot of the LA-ICP-MS analytical data of the zircon exposed in the 2.6 ct faceted sapphire SKG1
• Geological overview of the central Himalayan in Zanskar area (Kashmir, India) and location of the Kashmir sapphire deposit Sumjam in Paddar area (Mod-ified after Dèzes 1999 and Atkinson et al., 1983)
