I have a friend who owns a jewelry store. He has heard of the Yu He Liu Nian brand of Gong Shu Cultural Center. This jewelry has many styles and excellent workmanship, and many of them have anti-counterfeiting marks on the back, so you can start with confidence. No, I went to Chengdu on business last month and decisively bought a jade jewelry at their home. The color is really good, and it's quite conscience.
