Publishing a Video Book on Correct Geuda Identification

Accurate identification of suitable geuda sapphires before heat treatment is essential for successful enhancement. This year, we will publish a printed book on geuda heat treatment and identification. However, identifying geuda varieties using photos alone is challenging. Therefore, this project aims to publish a book with integrated video content. The video book will provide a more practical and visual approach to selecting appropriate geuda sapphires for heat treatment. This knowledge is highly valuable for gem traders, helping them make informed purchasing decisions.
