I found that the gold label of the gold shop is Au999, and the gold content of 999 and 9 gold labels only show thousands of gold but not gold content. What's going on here? isn't it ...
hello, there are two ways to name the purity of precious metal jewelry. (1) The literal representation is "thousands of pure gold" and (2) The purity representation is "au 999"
au 999 thousand pure gold Pt95 ‰
au 999 thousand pure gold 999.9‰
