The term "jade"refers to two different, yet
similar semi-precious metamorphic mineral gemstones, Jadeite and
Nephrite. Nephrite and jadeite are resistance to breakage and chipping
and due to their toughness they made a superior weapons and tools for
early man. Not until the 19th century that a French mineralogist
determined that "jade" was in fact two different materials. Nephrite is
usually only green and creamy white, while jadeite can have the full
range of jades colours.
Jade is mined in the regions of Canada, Australia, United States and
Taiwan.
