Yes, my parents customized a diamond ring for me at the bar mitzvah. If I remember correctly, it was at Qianjiang International. It is called oxygen jewelry. I forgot the specific house number. I will ask you next time. The boss is young but super professional, and the diamonds there are all GIA certificates. I want to say that they are much cheaper than Vientiane City. The boss explained that they are all brand premiums, which are very reliable.
