Wanning Hailing Pearl Farm

　　    　Located in Xincun Harbor, about 12 kilometers south of Lingshui County and facing Nanwan Peninsula across the water, it is one of China's well-known pearl farms. The pearl farm features a building connected to the sea by a long stone causeway, which looks like a platform from afar. Climbing onto the causeway, you can see shimmering blue waters dotted with rows of ropes, each floating with colorful plastic balls that resemble swim lane markers in a pool. Small boats weave in and out among the ropes, creating ripples — a beautiful scene across the harbor. The farm is famous for cultivating Pinctada martensii and Pteria penguin pearl oysters, supplying the nation with a significant quantity of high-quality pearls. In the 1980s, through collaboration with research institutions, the pearl farm successfully cultivated a large pearl measuring 15.5 millimeters in diameter, with a nacre thickness of 0.6 millimeters and a small attached pearl at one end. This is currently the largest artificially cultivated pearl in China, hailed as the "Pearl King" and ranked among the world’s top five renowned pearls. Here, pearl oysters are naturally cultivated in seawater. Visitors to the pearl farm can experience the fun of opening oyster shells and extracting pearls.
