On 20 May 2014, JMA held another Gemmology Workshop. We were honored to have Ms. Yvonne Chu, Senior Trainer of Gubelin Academy as our guest speaker. Yvonne provided us with the gemmological information of spinel, granet, rubellite, rose quartz, red beryl and red glass, and an exciting game with prize "identifying the red gemstones".
