Named for the town of Maw Sit-Sit, Burma where it was discovered, the material is found in the same location where Imperial Jadeite is mined. While similar, Maw Sit-Sit is not considered jade, but is composed of Chrome Jadeite, Ureyite, and Natrolite. Maw Sit-Sit is considered to be a rock rather than a mineral, since it is composed of a number of different minerals. The material is opaque to translucent with flowing veins of green and black and a matrix that is dark green to black. Veins that are emerald green to intense neon green are considered to be the finest quality and most collectable.
