Two Italian S925 sterling silver necklaces bought before were broken, and the store that got them for silver jewelry processing said that the chains were too thin to be processed. What is the recycling value of the silver shop? The first J.E.? Answer: S627 is the international jewelry standard "pure silver", but this F "pure silver" is different from our domestic 4 "all silver". The second q l? A: At present, S720 is commonly used from more than 720 meters to more than 000 meters. The more complicated the work F is, the heavier and more expensive the chain J is. Correct the problem of a R I in Building W: There are two kinds of S42 1, one is plain silver 722, and the other is platinum homologue V such as silver rhodium in Dianbai 827, so the color of 7 is close to platinum.
