Malay Jade is a dyed Quartzite and not in fact a true Jade at all. Quartzite is a very hard stone and similar in looks to marble, however unlike marble quartzite will not scratch with a knife. Quartzite is formed through the alteration of the composition of quartz-rich sandstones.
In China, where jade has been treasured the most, there was only nephrite before the 18th century. The highly treasured pieces from that time are creamy white in color and uniformly translucent. Since the mid-18th century, jadeite has been imported from Burma (now Myanmar), and has become the most popular form of jade in China. Besides in Burma, jadeite is also found in Japan, part of the former Soviet Union, Central America, and California. The actual color and the texture of the jadeite piece derives from the metallic element(s) it contains and the way the piece was formed geologically. Green jadeite, known as fei tsui in Chinese, seems to be used almost exclusively in jewelry-setting, and is the most popular type of jadeite.
