The Physics of Water
種水 (Zhong Shui)Before colour, there is Water. This refers to the stone's translucency and its ability to refract light. It is dictated by how tightly packed the microcrystalline structure of the Type A jadeite is.
An "Icy" piece has exceptionally high Water, allowing ambient light to pass deeply into the stone and bounce back, creating an internal glow. A piece with poor Water appears opaque and heavy. High Water is exceedingly rare, which is why a pure, colourless Icy bangle can command a higher price than an opaque green one.
