If you want to rest assured, go to Hangzhou Tower, where there is diamond processing, and the credibility of manual work is more reliable in all aspects.

Price: generally, it is gold price+loss+labor cost, and some of it is sold directly.

Now the gold price is 263 yuan/gram, and the loss may be 15-20%. Labor costs vary from place to place, and may be 2-300.

If you want, I can introduce the manager of Millennium Star Jewelry to take you there and enjoy the internal price. You can also ask some questions.
