I don't know this line of work, but I want to tell you that this kind of jewelry store is formal. (Small-scale exception) There is also a processing fee, which is also appropriate. Their service is to sell their products beautifully to customers, so don't be cheated. I also want to remind you that next time you'd better send this kind of information, ask first and then discuss it here, and then buy it all. Don't you think it's a little late to discuss this now? Because the goods sold in some places are non-refundable!
