Jewelry, unlike other commodities, is not guaranteed to be returned within seven days. The average jeweler won't let you return it if he is not satisfied.

There are two reasons. First of all, the price of gold changes every day. Secondly, any return needs to be inspected to see if it is original. Just look at the daily products, but the jewelry needs to be re-appraised by a special appraiser, which is not a small expense.

Of course, in this case, you can negotiate with the counter. Although it is impossible to return the goods for free, it should be refundable to lose a little.
