I bought pt999 from Hongsai Jewelry in Jiaozhou, Qingdao. I don't know the purity.

In addition to the style, buying gold now mainly depends on the gold content.

Generally, thousands of gold on the market are raw materials of 9995. Because the welding points need "solder" when ordinary thousands of gold are processed, the gold content of the whole jewelry after processing can not reach the original purity. There is also Wanjinjin, and he used nine thousand nine hundred and ninety-nine.
