However, before returning the goods, relevant valid vouchers should be prepared:

1. The purchase invoice must have a formal invoice that conforms to Chinese laws and regulations, and be stamped with the seller's invoice special seal with a clear name.

2. Quality problems, such as fake goods, must have a valid appraisal certificate from an authoritative appraisal institution, which has authoritative effect.

3. Time of purchase. Although there is no clear after-sales time regulation for jewelry and jade in China at present, according to the usual practice, it is an appreciation period within seven days from the date of purchase, which has the effect of returning goods.
