Ultra nano inclusion in blue sapphire from Diego, Madagascar

Ultra-nano inclusions in Be-containing natural blue sapphires (corundum) from Diego, Madagascar were observed and analysed by transmission electron microscope (TEM) and 3D atomprobe (3DAP). TEM results show that ultra-nano inclusion has 10 nm length and 2 nm width, and the nano-inclusion is identified by Wolframite structure (P2/c). 3DAP results show the inclusion consists of Ti, Nb, Ta, Fe, Sn.
