Named after jade, which is frequently composed of jadeite. Jadeite occurs rarely as crystal, but most commonly as the monomineralic metamorphic rock jadeitite which is often used as an ornamental gem and carving material, known as jadeite jade. The pearly jadeite is white when pure, often green or blue green up to black according to iron or manganese ions. Together with Nephrite, g.yang tri, it is one of the two rocks termed as jade. Both are extremely tough and resistant to fracture such that they have been used for making choppers and blades since Neolithic times. (mindat.org)
