In the jewelry market of some big cities, a kind of' ice seed' jade with good water head is transparent or translucent, generally white or off-white, with few white spots and ribbons and uneven distribution. This kind of jade is called "water nourishing" in Yunnan.

Water foam with blue ribbon is called' blue flower floating in water', and it is often processed into bracelets, pendants, sculptures, etc. and sold in the market of Taiwan Province Province. Simple identification can adopt the following three methods:

1, magnification observation method: the ink is mainly albite, not emerald, mostly white stone brain or cotton. This is ink.

2. Hand weighing method: the specific gravity of water mill (2.57 ~ 2.64) is much smaller than that of jade, and it has obvious light floating feeling compared with jade.

3. When you look at the grains through the light, you can see the grains of water foaming through the light. Its size is relatively uniform and its shape is different from that of jadeite.
