On the third anniversary of Mengshan Jewelry Store, No.76 Chaoyang Road, Xingning District, Nanning, I did another activity. I heard a friend say buy a diamond ring and get one for free. Do you know any friends? I don't know. Diamond rings are expensive when bought, but worthless when sold. A friend of mine bought a 50,000-dollar diamond, and later wanted to sell it for some money because of lack of money. As a result, he sold 8000 yuan. You don't want all the diamonds collected from that businessman, so just give them back to you and take them away. Because the quality of diamonds in China is very low, many of them can only be regarded as diamonds. Many of them have no certificates. Even if there is a certificate, it is issued by China Quality Supervision Bureau, Jewelry Association and other garbage institutions. They can do it for a few dollars, which is not recognized internationally. You should be careful when buying such things.
