AB - The color enhancement of natural ruby produced from Mong Hsu were carried out by the heat treatment using gas diffusion. The natural ruby in this paper has a colored patch of which the color ranges from blue to a color close to black. The most favorable heat treatment conditions were as follows; range of temperature 1400~1600oC, duration 12 hrs, O2 atmosphere . The color tone of ruby obtained under the optimum conditions was overall clear red by partial removal of colored patch. From EPMA results, part of blue or black colored patch within ruby were found to occur by charge transfer between Fe2+ and Ti4+. These results are consistent with the XRF that contents of Fe(Fe2+ or Fe3+) and Ti4+ ion to cause a blue or black colored patch after heat treatment became slightly less than with non-treated ruby. The silk formed on the surface of ruby heat treated for 12 hrs at 1700oC were found to be generated by re-crystallization of rutile TiO2 by XPS analysis.
