AB - Color enhancement of African rubies with dark red was caried out by the heat treatment and the hydrothermaltreatment method respectively. The heat treatment method brought about an adverse effect causing the color to bedeteriorated. However, the hydrothermal treatment method enhanced its color and clarity. The hydrothermal treatmentconditions for color enhancement of them were as follows: solvent: 0.9 M Na2CO3-1 M K2CO3, temperature: 450oC,duration: 48 hrs, filling: 30 %, presure: 375 atm. As the results of characteristics for African rubies obtained under theseconditions, it was known that the amount of Cr3+, Fe3+, Ti4+ was reduced after the hydrothermal treatment from the ICP/MSand XRF analyses. Also, it was found that the red color from the colorimeter analyses was getting lighter. These resultswere consistent with the PL analysis showing that the intensity of the luminescence peak generated by the electrontransition of Cr3+Key words African ruby, Color enhancement, Aggregation, Hydrothermal treatment method, Heat treatment method
