Also remember to ask the merchant for the jewelry and jade appraisal certificate with "CMA" and "CAL" marks. Usually, every precious piece of jewelry and jade has a certificate to ensure that the purchased jewelry and jade are consistent with the certificate, and the certificate is accompanied by photos. The first thing is to know the difference between jade and stone. Stone is most easily confused with jade.

For example, a piece of low-grade jewelry with the market price from 200 yuan to 300 yuan is priced at 3,000 yuan or 4,000 yuan. When consumers buy with a 10% discount or a scratch card marked with a winning amount of 2000 yuan, the supplementary payment paid far exceeds the actual value of jewelry.

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.
