This red, when it was better, maybe the technology is not very prosperous, people also Very simple, there won't be much big things. At most, the quotation is a bit high. I can't afford it, but it can be different now. As long as it is red, it is a fake. It is difficult to distinguish between true and false. through.
Nowadays, the fake techniques in shopping malls are getting more and more superb. Xiao Bian summed up some common jade falsification techniques. There are two types of fraud in the jade, the fraud of the products and the fraud of the original stone.

People use the foundation to cover the cockroaches on the face; while the fake jade "plays the foundation" is actually a fake inferior goods and a low-grade jade. Why not pretend to be a high-grade jade? This is because the former market is usually squandered with high-grade jade, and for a long time, Cuiyou has been wary of high-grade jade, so they aim at the middle and low-end, such jade is not high, usually good quality. Plus listing, sweet words, easy to make people suffer and be deceived.

Therefore, when the cotton is scrubbed with alcohol, the color will fall off, and the natural jade will not present. Kind of situation.

Ice Cui is not an "ice jade". It is actually a kind of glass. It is easy for the first-time brothers to suffer because of the green color and the contrast.
The way to identify: If you see a jade like a beer bottle, the offer is also a few bottles of beer, then it must be such a fake.
5, the stone becomes jade
In the end, this kind of falsification method was once exposed by CCTV, that is, jadeite cooked with ordinary stones, which is low in cost and harmful to human health through industrial processing.
The way to identify: This kind of jade, you need the necessary testing tools to be able to see, the best way is to pick a good reputation business purchase.
