Jadeite vs Nephrite
Jade, or yu ( 玉) refers collectively to two different gem stones: Jadeite and Nephrite.
Jadeite
A gem stone made up of silicate minerals that consist of sodium and aluminum-rich pyroxene. It has a Mohs Hardness of between 6.5 and 7.0 ['ying yu' ; 硬玉 ;'hard jade']
Nephrite
A gem stone made of silicate minerals that consist of calcium and magnesium, nephrite belongs to the amphibole group of minerals. It has a Mohs Hardness of between 6.0 and 6.5 ['ruan yu' ; 軟玉 ; 'soft jade']
Jadeite is rarer than nephrite and is therefore regarded as more valueable. Nephrite mines are located in China, Russia, New Zealand, Guatemala and the Swiss Alps. Dark green jade,(Canada jade) is also found in Western Canada. Jadeite mines are in China, Russia and Guatemala, but the best Jadeite stones come from Burma (Myanmar).
Jadeite, with its bright emerald-green, lavender, white (bai yu : 白玉), pink, reddish orange and brown colors was imported from Burma to China only about late 1800s. The vivid green variety became known as fei-ts'ui ( 翡翠) is the most expensive of the Jadeite and commonly used in jewelry setting.
