Look at the mark inside the ring first to identify that the product belongs to the company, and negotiate to change the style.
Second, go to other jewelry stores to investigate or understand the situation and see if other jewelry stores handle similar situations in this way. Receipts, invoices and insurance policies have all been lost. If there is no invoice and voucher, the jewelry store can't find the invoice stub when the consumer first bought the diamond ring. If the consumer wants to exchange the goods, the jewelry store can evaluate it, and the consumer can also exchange the goods after making up the difference, so be sure to keep the invoice of the diamond ring.
