In the jewelry market of some big cities, there is a kind of 'ice type' jade with good water head and transparent or translucent. The color is white or grayish white overall, with less white spots and ribbons, and uneven distribution. Locally known as 'water scorpion' in Yunnan, the band with a bluish tint is called 'water floating blue flower', which is often processed into bracelets, pendants and carvings for sale in the Taiwan market. In fact, the main mineral component of 'Water Foam' is albite, followed by a small amount of pyroxene minerals and amphibole minerals. Simple identification can be done in the following ways:
1. Magnification observation method: The water mill is mainly composed of albite, which is not green, and has more white stone brain or cotton. This is the water foam
2, hand rub method: the proportion of water mill (2.57 ~ 2.64) is much smaller than the proportion of jade, the hand rub is more light than the jade.
3. Determination of refractive index method: The refractive index of water mill (1.52~1.54) is much smaller than that of jadeite.
4, look at the luster, the water foam is relatively weak, which is due to the low refractive index.
5, look at the characteristic bubble string of water foam, pay attention to the general is not a big bubble, but usually very small, parallel small bubble string, thick look like crystal grain, will be found under the magnifying glass is a small bubble string, but small The bubble string may be filled with impurities to form fine floating flowers.
6, the light sees the grain, the light can see the grain of the water foam, its size is relatively uniform, the shape is different from jade.
