Mogok is a city in the Pyin Oo Lwin District of the Mandalay Region of Burma (Myanmar), located 200 km north of Mandalay and 148 km northeast of Shwebo.At 1170 meters in elevation, the city has fairly temperate climate year-round, and is home to mostly Bamar, with large minorities of Shan, Lisu, Palaung, Karen ethnic groups, as well as Chinese, Indians and Gurkha.
Mogok and other villages nearby have been famous since ancient times for its gemstones, especially ruby and sapphire, but semi-precious stones such as lapis lazuli, garnet, moonstone, peridot and chrysoberyl are also found. The gems are found in alluvial marble gravels by means of panning, tunneling and digging pits by hand. There is little mechanization of the mining. The gravels derive from the metamorphosed limestones (marbles) of the Mogok metamorphic belt.90% of the World's rubies come from Myanmar.
