Beijing Lan Se Ai Sha Co., Ltd. is the owner of the JIANGXIN brand and an international manufacturer of wholesale fine jewelry.

Our main office is in Beijing, China, while design and manufacturing are headquartered in Shanwei City, one of China’s most prominent industrial centers for jewelry manufacturing.

OEM Service:
We can stamp your brand name on your customized jewelry since our jewelries don’t have our own brand except for S925 or 990.

Do you have your own design that you need us to produce? Our quality control systems and high-end factory ensure that we can rapidly supply precisely the products and service you need.
