Bracelet identification
(1) Look at the color.
Mouth: "The color is not correct, the color floats without roots."
1. Color evil, flash! This is mainly manifested in green, and now many C, B+C are mainly dyed green. For purple: white bag purple is more likely to be natural; if it is purple, the novices should be careful. If you dye other colors, the eagle will not say much here, wait a few days. Engage in a new post, and talk about it with everyone. In short, C Cui gives people the feeling that color is not right, evil!
2. Can't see the excellent root, flash! The main performance is that the color floats on the surface, there is no transition from the inside to the table, or it is not obvious. What should be specially stated here is that the means of fraud is becoming more and more sophisticated, and there may be color roots in the dyeing. Everyone has to judge from various methods to get accurate conclusions.
(2) Look at the germplasm.
Mouth: "The germplasm does not match."
This is mainly for some jadeites, its granules are very thick, but overall it gives a feeling of long water head, this phenomenon should not be the phenomenon of natural jade. (Of course, except for some jadeites that have recrystallized) Newbies see this thing and flash quickly! The old bird judges by other means.
(3) Look at the surface.
诀çª: Orange peel phenomenon and acid crack.
Tip: Pick up the bracelet, under the light (what light is OK), adjust the position of the bracelet, catch the reflective spot on the surface of the bracelet, see if there are any pits and acid cracks on the surface, if any, the novice will flash immediately! Take out the magnifying glass and it will be laughed by the expert! What is special is that some oranges with high B can also have orange peel effect. So, don’t hang on a tree, change it. If it doesn’t work, Come, come to Yulin to find the eagle, the eagle will help you to see, by the way, please also eat a bowl of Yulin's burdock powder, the famous 哟!!
(4) Look at the texture.
Method: Pick up the bracelet, face the light, pay attention to this to transmit light (the third point above is not using transmitted light). If, the texture inside is very messy, serious like mesh and tree roots, novice, flash! veteran, be careful!
(5) Find the shortcomings (impurities).
In general, the green of A cargo will have some impurities. After all, the natural stone texture can be purely wherever it goes. If it is too pure, the price is estimated to be beautiful! You can try: green to find black, white Looking for yellow, and,,,, the eagle keeps a little, the next post and then talk to everyone in detail. In short, everyone remembers: A goods Tsui Cui is definitely not a "pure girl"! Accept its flaws beauty!!
(6) Listen to the sound.
Steps: 1. Prepare an agate stick, a rope. (General business has it, you must ask him, don't look at the face)
2. Lift the bracelet with a rope and take care not to take it by hand!!
3. Gently tap the bracelet with an agate stick (note that the agate stick is correct! Coins, keys, other DDs are inaccurate!)
4. Sound: The sound of A goods is more melodious, like the sound of a wind chime! B goods, refers to the jade that only washed the ground. Sound, dull, hoarse. Some slightly pickled DD, 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: ZZ of different germplasm, it is estimated that the sound of knocking out will be different, and this year, the eagle has seen several tens of thousands of bracelets for others, it is high B, the sound is better than the general A goods ZZ, so There is no way to identify Cui Cui! Be careful!
