Good diamonds are certified. Ordinary diamonds and diamonds of about 0.5 carats are generally GIA certificates, which seems to be Belgian. If there is no certificate, there is no way to guarantee the quality. Whether a diamond is good or not depends on factors such as clarity and cutting. In addition, the diamonds of Chow Tai Fook and Xie Ruilin are bought from big diamond wholesalers, and the colors are basically I-J (the whitest color is preferably D, so I can calculate the grades myself). I have traveled all over Beijing and found nothing whiter than this. It is suggested to go to Beijing Mutton Hutong Jewelry Trading Center to buy diamonds, and then find someone to process them. The E-colored diamonds we bought there are also very well cut, which is three or four thousand cheaper than the shopping malls. But Chow Tai Fook's style is good. You can look at the style of the ring holder first, and then find a special store to process it. Cost-effective, but also can buy better diamonds!

If you can go to Hong Kong to buy Chow Tai Fook, it will be cost-effective, the price will be several thousand yuan lower and the style will be relatively new.

I just got a customized diamond ring yesterday. Good luck to you, too:)
