Identification method of true and false jadeite;
Observation method: Due to the characteristics of polycrystalline structure of jadeite jade, colloid or dyed pigment hidden in the cracks of crystal structure in artificially processed products can be observed with a high magnification magnifying glass, and the acid-etched reticular surface or impregnated reticular pigment can be seen.
Dropping method: natural jadeite is dripped with concentrated hydrochloric acid, and sweat will appear on its surface within a few seconds or minutes; There is no such phenomenon in artificially processed goods. ?

Tips for buying jade:
1, look at the color. See if the color is pure, rich and uniform, and use a spotlight flashlight to check whether there are hidden variegated colors.
2. Observe transparency. Observing under strong light, the higher the transparency, the better.
3. Listen to the sound. The knock on the door is crisp and pleasant.
4. Observe emeralds and stone flowers. According to light observation, jadeite has the flash of other mineral particles (namely emerald), and there are often massive white flowers called stone flowers. Both of them get twice the result with half the effort.
5. Look at cracks and dark spots. Some cracks exist in the raw ore, and some are caused by processing, so the less the better; Black spots are everywhere in jadeite, so it is better to have fewer and smaller ones.
6. Look at the processing level. Smooth surface, good polishing and good shape are preferred.
