You can't know this until you see the product. You can communicate with the jewelry clerk before buying it, and how long it will take to return it. What are the conditions? If possible, you can go directly to the gold jewelry quality supervision and inspection center to check if there is any problem after you buy it. The inspection time is usually the same day. It takes about 1 ~ 3 days when you are busy. If you are lazy and worried, find another famous brand.
