Treasure Hunting Site

　　   Local residents have long shared stories of uncovering extremely valuable gems while mining, and these tales are widely circulated. In 1998, a new gem-rich mine was discovered on the Chinese side of Ruili within this mineral belt. After reconnaissance and site surveys conducted by the Fourth Geological Brigade of the Yunnan Provincial Bureau of Geology and Mineral Resources, evidence confirmed the presence of red and blue corundum, as well as red spinel, almandine, and other gemstones. Samples were processed and appraised by the Gemstone Research Laboratory of the China Geological Museum and the Gemstone Appraisal Laboratory of the Ministry of Geology and Mineral Resources. Within an evaluated area of 1 km², the alluvial deposit was found to be quite extensive, with gem minerals visible throughout the gravel layers—especially in the midstream section of the river (where the current treasure hunting site is located), where gem content was highest. Based on this discovery, and with approval from relevant authorities, Ruili launched the country’s first unique travel activity that combines luck and participation: gem treasure hunting.

　　   The NanGu River Treasure Hunting Site was established in the most gem-rich segment of the mineral belt—Nongdao’s Nangu River—covering an area of 600,000 square meters. Along the banks of the Nangu River, there are rows of ethnic-style buildings, including a comprehensive service building that integrates dining, gemstone appraisal and processing, and shopping, as well as leisure and entertainment centers, guest rooms, and more. Visitors participating in treasure hunting use designated tools to search for gems. The raw gemstones they find can be handed over to specially hired Burmese gemstone craftsmen for appraisal and on-site processing into rings, necklaces, bracelets, and other gemstone jewelry. The hidden opportunities in treasure hunting mean participants may become lucky at any moment—it’s endlessly exciting. The joy of participation and the thrill of discovery have made this tourism activity widely popular and well-received since its inception.
