YANGON, Myanmar: An enormous jade boulder that weighs up to 192 tons has been found in Myanmarâs restive Kachin State, officials said Saturday. The 174,600-kilogram raw jade stone was discovered in a gem-rich region of Hpakant Township in northern Kachin on Tuesday, according to an information ministry statement.
Jadeite is one of two forms of jade. This beautiful gem is loved in jewelry for its striking green color, but jadeite gemstones were actually originally used thousands of years ago as weapons. Jade's toughness made it ideal for carving into ax heads and tools as well as ritual artifacts.
