--- . \\ Peter C. Keller and Wan Guo-dong . THE CHANGMA DIAMOND DISTRICT, MENGYIN, SHANDONG PROVINCE, CHINA \\ Since the early 196Os, Chinese geologists have conducted extensive exploration for diamonds. One of their most important discoveries to date is the Chnnglna kimberlite district in Shandong Province, which encompasses two pipes and eight dikes. The most active mine currently, the Victory No. I, produces approximately 6,000 ct of diamonds annually, 20% of which are gem quality. The ore is processed locnlly and the rough stones ore given a preliminary sort before they are sent to special factories for cutting. Large, goodquality stones have been recovered at Changma; the largest to date weighs more than 119 ct. ( ) - https://www.gia.edu/doc/The-Changma-Diamond-District-Mengyin-Shandong-Province-China.pdf
