1 texture. Naturally transparent or translucent, the surface is oily and lustrous. Careful observation reveals a slightly rounded, slightly transparent "salt grain" and fibrous material surrounding it.
2 hardness. Natural jadeite is jadeite, the Mohs hardness is 7 degrees, and it is scored with sharp tools, leaving no traces; the fake jade has low hardness, and the sharp knife can draw traces.
3 green. The natural jade looks at the strong light, and it can be seen that there are other green mineral glitters, which are called green flowers or green. The fakes made of glass, plastic and porcelain have no such "green" characteristics.
4 relative density (specific gravity). The natural jade structure is hard and compact, has no bubbles, and has a high density. The sound is crisp when struck; the fake product has a loose structure or bubbles, and the density is small, and the squeaking sound is not crisp.
5 colors. The authentic green color is pure and pure. Some fakes are made of white jade, serpentine, Australian jade, Korean jade, marble and even miscellaneous stones. After decolorization, they are filled with high-hard plastic pulp and added for color treatment, or immersed in green liquid to make "additional jadeite". "Under the strong light, the green lines are visible, messy and small; some are not grainy, but the turbidity is unclear, the gloss is poor, and the weight is lighter than the original."
6 listen to the sound. Steps: 1. Prepare an agate stick, a rope. (General business has, you must ask him, do not look at the face) 2. Use the rope handle bracelet to hang up, be careful not to take it with your hands! ! 3. Use agate stick to gently tap the bracelet. (Note that the agate stick is correct! Coins, keys, and others are inaccurate!) 4. Sound: The sound of A goods is clear and melodious, like the sound of a wind chime. Listen! B goods, refers to the jade that only washed the ground. Sound, dull, hoarse. Some slightly pickled bracelets, the sound is clear, but short, there will be no melodious echo! C goods, sound, dull, hoarse. It's like picking up the sound of two keys knocking on each other. Note: Bracelets of different germplasm are estimated to have different sounds. The current fake technology is super high, and the sound is more careful than the general A cargo bracelet.
