Qingdao diamond, where can I customize it?

Let's go to Enoch's house. It's on the 25th floor of the flagship building of Cyberport. I feel that his home is quite good, with low price, good service and perfect after-sales service. I am fatter now than when I got married, and my ring is tight. His family changed the size for free and gave me a beauty treatment, as new as when I just bought it. His beauty said that all after-sales services are free, which is really sweet! !
