The gold in Shuibei Jewelry City must be gold, true or false, mainly depending on the gold content. It is written that high solder joints will make the goods have insufficient gold content, so they can be taken to the testing station for testing, but I don't think it is necessary to spend so much money on testing. You can buy a bigger brand and feel more at ease. Some jewelry companies cooperate with the inspection station, and all the goods are coded on the labels. You can go to the inspection station in official website to check.
