The Baorui Diamond Jewelry Lottery is a fake. Jade jewelry is different from ordinary goods, and its pricing range is large, which is difficult for ordinary consumers to distinguish. Many merchants promote jade as real jade, but the grade is low, which is inconsistent with the selling price. Baorui merchants bid for jewelry at high prices first, and then sell it at the jewelry counter through a free lottery. Lottery tickets are fake, but in fact they buy jewelry at a high price. Baorui Diamond & Jewellery Company is an organization providing jewelry evaluation and sales services. It will provide a jewelry appraisal certificate issued by an authoritative organization with detailed jewelry appraisal information, including weight, color, size, purity and so on. Consumers can judge the authenticity of jewelry by checking whether the information on the certificate is consistent with the product.
