Abstract

In this study, we observed Be-containing natural blue sapphires from Diego, Madagascar by TEM and there were nano-inclusions which have 20-40nm length and 5-10nm wide. Those consisted of Ti, Nb, Ta. By LA-ICP-MS analysis, we found a good relationship among Be, Nb and Ta, so The consistent of Be has a relationship with nano-inclusions.
