Donghai Crystal Carving and Jewellery Trade

Jiangsu's Donghai Crystal Industry Regulation defines Donghai County as the main concentration of raw-material trading, design, processing, branding and sales. It defines an industry, not proof that every stone sold there was mined locally. Jiangsu Donghai Crystal Industry Development Group runs the Crystal City trading venue; Donghai Hengda Jewellery cuts, polishes and carves stone; Donghai Zhishanfang Crystal Culture designs, makes and sells crystal goods, including online. They are separate legal persons with different roles. Current local reporting shows the market and workshops operating, but county transaction totals are not any firm's revenue. A buyer should check mineral type, stated origin, natural or treated condition, dimensions, design rights and labels, and not mistake a market operator for the maker of every tenant's goods.
