Jewelry stores recycle gold without invoices, but the price will be reduced accordingly. Relevant persons of ICBC Beijing Branch said that because the repurchase area of the precious metal sales repurchase center is equipped with professional testing equipment and personnel, even if the customer's purchase vouchers, receipts, product certificates and other relevant certificates are lost, they can be repurchased as long as they pass the inspection. Therefore, the detection cost is high, and the repurchase cost is correspondingly increased. After the gold product passes the test, the customer's repurchase funds will arrive in real time. Investors should pay attention to the fact that products such as gold ornaments can only be tested by destructive testing methods. Once the fineness of gold is insufficient, customers can only get back the melted gold products, and can't return to the shape before inspection.
