Men aged 30-40 will buy some jewelry, usually some men's rings and beads, and they have hundreds of thousands of financial resources to spend. The main reason is that the gold they bought is more valuable and can appreciate for a long time. If you don't recognize big brands, it will be cheaper and the goods will be the same. I am engaged in the gold jewelry industry and recommend bead chains. This has been popular for many years, and it is still very popular now, which shows that some people are very classic. . I hope this helps.
