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 the two minerals called jade. The other jade mineral is nephrite, which is a variety of actinolite. Jade has been used for eons in China and Central America as an ornamental and religious stone of deep significance. The nephrite jade was used mostly in China, although both have been used in both regions. Nephrite is more abundant than jadeite and has few color varieties, ranging only from creamy white to green. Jadeite is found in strongly metamorphosed sodium-rich serpentinous rocks, and is named from the Spanish piedra de ijada (stone of the side) as it was thought to cure kidney stones and other kidney ailments.
