中国金刚石矿资源比较贫乏。全国只有4个省产有金刚石矿。探明储量的矿区有23处，总保有储量金刚石矿物4179千克。从地区分布来看，主要产于辽宁，其储量约占全国的52%；山东蒙阴金刚石矿田次之，占44.5%。在矿床类型方面，我国金刚石矿以原生矿为主，砂矿(湖南沅江流域、山东沂沭河流域等地砂矿)次之。金刚石矿成矿时代以古生代和中生代燕山期为主，第四纪砂矿亦具一定的工业意义。
到目前为止，世界上发现的最大天然金刚石叫“库利南”，重达3025.75克拉（5克拉等于1g），1905年在南非发现。它在加工时被切成两大块和几十小块，其中最大的一块叫“非洲之星1号”琢磨后的重量为503.2克拉。英国女王把它镶嵌在自已的皇冠上。1977年我国在山东临沐县发现了一颗无色透明，重158.8克拉的金刚石——常林钻石。

China diamond mine resource is relatively poor. There are only 4 provinces in the province of diamond. Proven reserves of 23, the total reserves of 4179 kg of diamond mineral. From the regional distribution, mainly produced in Liaoning, the reserves accounted for 52% of the country; Shandong Mengyin diamond ore field, accounting for 44.5%. In ore deposit type, the diamond mine of our country mainly to primary ore and alluvial placer (Hunan Yuanjiang River, Shandong Yishu River Basin, etc.). The era of diamond mineralization in Paleozoic and Mesozoic Yanshan period, quaternary placer also has certain industrial significance.
So far, found in the world's largest natural diamond called "Cullinan", weighing 3025.75 carat (5 carat equal to 1 g), discovered in South Africa in 1905. It was cut into two pieces and dozens of pieces, one of the largest of them called "the star of Africa, 1," the weight of 503.2 carat. The queen of England set it on its own crown. China in 1977 in Shandong County, Lin Mu found a colorless and transparent, the 158.8 carat diamond -- Chang Linzhu diamond.
