Jade jewelry is not bad, the company is in Shenzhen, which is a relatively large company. Before Emerald, I worked as an OEM for Chow Tai Fook, and my craft was not bad. Jade has been promoting the "Dazzling Dance Gold" series, which is unique in shape, beautiful in appearance and exquisite in craftsmanship, as if using some kind of cold and high pressure technology. Green advertising is not well done, so the public doesn't know much about this brand. Emerald gold is well done, mainly platinum, followed by k gold and jade. Mainly pure gold (not inlaid). Take mine. I typed it word by word. If you want to know more about other jewelry brands, you can add me. I am a jewelry major, and my knowledge is OK.
