First of all, distinguishing the gold content requires professional instruments, and there is a simple method to calculate the density, which is also cumbersome to do. Secondly, what is meant by burning with fire and alcohol is a lie, and it is impossible to tell the difference.

Jinliufu is also a well-known brand, and there should be no problem in carving thousands of gold earrings!
