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 rarer than nephrite and is therefore regarded as more precious. Nephrite deposits have been found in China, New Zealand, Russia, Guatemala and the Swiss Alps. Dark green jade, so-called Canada jade, is also found in Western Canada. Jadeite is found in China, Russia and Guatemala, but the best stones come from Burma, now known as Myanmar. There, at the annual 'Gems, Jade and Pearls Emporium', blocks of jade in all sizes are auctioned.
