Studies have been carried out using the advanced spectroscopic techniques namely, Photoluminescence, UV-Visible, FT-IR, Raman and EDXRF analysis. The results obtained from the studies shows the predominance of colour causing element Cr and other associated elements like, Ti, V and Ga in Red variety of corundum than the abrasive corundum crystals, while Fe is found predominant in colourless or abrasive variety. From EDXRF studies the presence of impurity ions in the crystal lattice is quantified and its effect on the corundum crystal has been ascertained.&#13;
