In the early 1990s, Donghai people used the unique crystal resources to enter the market step by step in the form of "carrying baskets for small sales". Since being awarded the title of "Crystal Capital of China" in 2003, our county has paid attention to the scale, branding and international development of crystal industry, highlighted the inheritance, innovation and exchange of crystal technology, and actively expanded the industrial development space. China Donghai Crystal City, China Crystal Museum, China Crystal Culture Creative Industry Park, Zoje Crystal Culture Industry Cooperation Park and other unique crystal industry development platforms have been established, covering raw material procurement, one museum and two parks.

There are nearly 250,000 crystal employees and more than 3,000 crystal processing enterprises in the county, forming an annual production scale of 30 million pieces of crystal ornaments and 5 million pieces of crystal handicrafts, with an annual turnover exceeding/kloc-0.00 billion yuan. Among them, Crystal Cultural Creative Industry Park has introduced five national masters of arts and crafts, including Wu Jianmin, Wei Dunxu, Cao and Xu, and 33 important crystal jewelry processing supporting enterprises and cultural media organizations, including Hailong Crystal and Shilaiyun. Today, Donghai crystal has become the gathering place of the world crystal from its original place of origin. Last September, the World Arts and Crafts Council officially awarded the East China Sea the title of "Crystal Capital of the World".
