    Myanmar

    The history of Burma’s jade mines in the West is a brief one. While hundreds of different reports, articles and even books exist on the famous ruby deposits of Mogok, only a handful of westerners have ever made the journey to northern Burma’s remote jade mines and wrote down their findings. Occidental accounts of the mines make their first appearance in 1837. Although in 1836, Captain Hannay obtained specimens of jadeite at Mogaung during his visit to the Assam frontier (Hannay, 1837), Dr. W.Griffiths (1847) was the first European to actually visit the mines, in 1837 (Griffiths, 1847).
