First: if it is jewelry, there will be a detailed description of the product in the invoice and manual when you buy it. You can apply to the component appraisal unit for appraisal, and then complain to the merchant, 3 15 and the industrial and commercial bureau!

Second: if it is an investment gold bar, it is generally sold in major banks and gold shops. It is impossible for a store without strength to sell gold bricks. This kind of gold bar will have an appraisal certificate, and the possibility of insufficient purity is very small! This situation is not expected to happen to the subject. Generally, if you have an appraisal, nothing will happen!

Third: gold has good ductility, and it is normal to realize it, but it is not afraid even if it is deformed. Changes in physical properties will not affect chemical properties, so the composition will not change. If you have a manual or an appraisal book, you can find an authoritative appraisal center for appraisal. You can go to the industrial and commercial bureau 3 15 for the final lawsuit!

Good luck to the landlord!
