White mutton-fat jade is the most valuable of all Chinese jade available, and material from Hotan is considered the finest nephrite in the world. Hetian jade is almost 99% pure tremolite, and with nephrite, the more tremolite it contains, the more valuable it is. The finest quality jade from Hetian has a buttery luster and creamy color like no other jade on earth. Of the many varieties of Chinese jade, Hetian jade is considered to be one of the most valuable, and also happens to be the most well-known of jade varieties. Burmese jadeite is also extremely valuable, and white or creamy color jadeite is highly sought-after by collectors, especially throughout Asian countries.
