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 beautiful, and rare, and even though itâs a relative newcomer in the Asian jade trade (the 1700s) it became Chinaâs pre-eminent gemstone over the past two centuries, and thatâs at the root of the confusion between the two stones. (The Chinese use the word âyuâ to refer to both kinds of jade.)
