Abstract
The main purpose of this study is to observe the abundant inclusions of blue sapphire samples from Australia and analyze the composition of inclusions and provide a theoretical basis for the identification of its origin.The Leica M205A microscopic camera was used to finish the image acquisition of characteristic inclusions in blue sapphires from Australia. Laser Raman spectrometer was used to test inclusion composition.The result showed that the sapphire samples generally had obvious uneven colour distributions, healing fissures and partings. Some samples have hexagonal ribbons. Microscopic observation showed solid phase inclusions, tubular gas-liquid inclusions, fingerprint inclusions, and occasionally three-phase inclusions.Specially, some inclusions occur in the form of bicrystals.The inclusions identified by Raman spectroscopy include zircon, rutile, anatase, hematite, niobite, nepheline and CO2.
