* * No * *, Wuhan Jewelry Appraisal Center does not need consumers to provide purchase invoices for appraisal. Consumers only need to bring personal jewelry products, valid identity documents and purchase related documents, including invoices, certificates, labels, quality guarantees and so on. And go to the designated eight pilot testing institutions for free testing. Jewelry identification is to identify the types, purity, synthesis, labor, processing and some origin characteristics of all jewelry, jade and organic gemstones, which can accurately identify the authenticity of jewelry and protect the rights and interests of buyers.
