Buying gold bars and playing with jewelry outside, how to prevent gold shops from stealing gold for gold? How much is the general loss? Why is every family different?
You can't prevent this situation at all. Suitable for tampering in processing. You are not a professional jewelry processor, but gold will be damaged during processing. This is normal. Generally speaking, the loss is around 3%. If you want to process it, you'd better take it to a professional jewelry store for processing, which will be guaranteed.
