There are many folk jade test methods circulating in the jewelry market. Many people like to use these methods to check when purchasing jade jewelry. In fact, many folk testing methods are not scientific and reliable, not only can not identify the true and false of jade, and even damage your jade!
Wrap hair
Reliable index ★ ☆ ☆ ☆ ☆
This method is to use hair strands wrapped around the jade, burned with a lighter, and immediately broken is fake, burning is always true. In fact, the fire has an inner flame and an outer flame. The temperature of the outer flame is much higher than the inner flame, and the tightness or looseness of the hair strand has a great influence on the result. It can be said that this method is simply out of nothing and does not work.
It’s true jade
Reliable index ☆☆☆☆☆
Many people think that the hardness of jadeite is very high, and it is true jade that can touch the glass. Is it reliable?
First, the composition of the glass is quartz, the Mohs hardness is 7, and the hardness of the jade is 6.5-7. Secondly, the glass is cryptocrystalline, and the hardness is uniform in each orientation; the jadeite is polycrystalline, and its cleavage surface has poor hardness. Therefore, in the process of sliding the glass, the jade may be damaged to some extent. This method can not only identify the true and false jade, but also may lose a good jadeite!
The sound of the percussion is really jade
Reliable index ★ ★ ☆ ☆ ☆
The denser the crystal particles of jadeite, the smaller the influence of sound wave propagation, and the crisper the sound will be when tapping. The B-car jade has been damaged by acid pickling, and its fiber interweaving structure has been damaged and become loose, so the knocking sound is relatively dull. Therefore, many people use the jade knocking sound to judge the true and false. Looks like it is very reliable?
In fact, with the development of counterfeiting technology, this method is not so reliable now. Now the B goods, the filling has made great progress, and the B-selling sound of the improved filling is also very crisp. In addition, the knocking sound is not only related to the density, but also related to the stone pattern. The stone jade A-Jade percussion sound is also a bit dull~~ And, if it is small beads, ring faces, mosaics, these are small Jade, how do you knock? Therefore, this method is also not feasible.
Drip method
Reliable index ★ ★ ☆ ☆ ☆
Since the production process of B-Jadeite is still relatively backward a few years ago, there will be obvious acid-etched netting and acid-etched pits on the surface of the jade. The water drops will not be rounded after the drops, and the surface of the A-Jadeite The water droplets are round. Well, it seems that this method is more reliable! really?
All said, the road is one foot high and one foot high, technology is improving, technology is innovating! In recent years, the B-Jadeite jade will be subjected to secondary polishing. After this process, the acid-etched netting and acid-etched pits on the surface of the B-Jadeite jade are gone under the ten-fold magnifying glass! Therefore, the old jade may still have some use, encountering high-tech B goods, the dripping method has already been egg-shaped??
