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.
Most jade on the market is composed of nephrite; jadeite jade is quite rare and in its emerald-green, translucent form is referred to as Imperial Jade or gem jade. A small amount of Cr in jadeite accounts for the color of imperial jade. Other color-based names for jadeite jade are Yunan Jade, for a uniquely appearing dark green, semitranslucent jade, Apple Jade for apple (yellowish green) green jade, and Moss-in-Snow for white jade with vivid green spots and streaks.
