Trick 2: Look at the structure. If we can't judge the authenticity by identifying the luster of jade, we must identify the structure of jade. Looking at the jade structure, the first thing to look at is whether there is a "flying wing" phenomenon in jade.

No, jewelry counters all over the country have free sweepstakes, and then win the grand prize and buy jewelry at a low discount. And these merchants put those inferior jewels and jade at high prices in advance, and then let consumers buy these inferior jewels and jade at a discount n times higher than the purchase price to make huge profits.

It should be fake. At the stall selling jade in front of the supermarket, the lottery after supermarket consumption is the basic routine. Some relatives got a 10% discount coupon in the lucky draw, and spent 298 yuan and 498 yuan to buy Hetian jade pendants worth 2980 yuan and 4980 yuan respectively. They thought they had got a big bargain, but they were quietly framed.

This kind of lottery is actually a means for jewelers to dump low-grade goods, and they can also dump high prices through this means. The usual practice of these jewelers is to increase the price of low-grade goods by 10 to 20 times on the basis of the original price, and then mark all the so-called lottery tickets with discounts, first prizes or a certain amount of RMB.
