Olympus Tokyo JM Trinocular Gem Microscope Vintage. Condition: Both light sources work. Some light scuffs and markings on the body. Please see photos for detailed cosmetic condition. Both light sources power on, no further testing done. Economic development in Japan triggered a gem boom, but the market was flooded with fakes. Jewelers needed to distinguish between counterfeits and genuine articles. Under the guidance of Zen Nihon Houseki Kyokai (now the Gemmological Association of All Japan), Olympus developed the JM Gem Microscope. It was launched in 1967. The microscope used the same head as the SZ Stereo Microscope. The illumination system featured a dark/bright field illumination device as well as a focal illumination device. The JM was brought into action against fake gems, identifying natural gemstones such as rubies, sapphires, emeralds, and diamonds. Olympus G 10X 22 Japan (x2). 7″ x 11″ x 20.
