It is normal to have losses. For example, the gold jewelry we buy is getting smaller and smaller after a period of time, which belongs to natural wear, but it is a little more than 0. 1 g back and forth, and it is usually worn at about 0.0 g.

Peeling is rare. It is estimated that the degree of platinum is not good either. Generally, the jewelry color of 18K gold will be lighter, and 18K gold is mainly sold by technology, so its value preservation is not very great.

Diamonds should look at 4C standards, and diamond jewelry should not be blindly followed.
