(Addis Ababa University, 2025-04) Kibirite Mokonen; Mulugeta Sisay (PhD); Aselefech Mitiku (Mrs.) Co-Advisor
The Borena Zone in the Oromia Region of Southern Ethiopia has recently emerged as a significant source of sapphires. Despite the region's potential, local processing methods remain rudimentary, often relying on manual labor and traditional techniques that limit the quality and market value of the gemstones. This study explores the current state of sapphire processing in the Borena Zone and proposes technological enhancements to improve the efficiency and quality of the final product. From Mining Engineering point of view, integrating advanced processing techniques, such as cabochon style and Faceting, the sapphire industry in this region can significantly elevate its quality of the mineral; Sapphire. Successful case studies from other regions, including Sri Lanka and Madagascar, highlight the transformative impact of modern processing technologies. Implementing these advancements in the Borena Zone has the potential to not only increase the value of Ethiopian sapphires but also foster the quality. and strengthen the local gemstone industry's global competitiveness. This project work underscores the critical need for technological investment and skill development to achieve substantial process enhancements in the Ethiopian gemstone sector.
