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.
Translucent emerald-green jadeite is the most prized variety, both historically and today. As quetzal jade, bright green jadeite from Guatemala was treasured by Mesoamerican cultures, and as kingfisher jade, vivid green rocks from Burma became the preferred stone of post-1800 Chinese imperial scholars and rulers.
