珀匹盖陨石坑-
俄罗斯科学院西伯利亚分院表示，西伯利亚东部的珀匹盖陨石坑内有“数万亿克拉”的“冲击钻”，是良好的工业钻石，而不是用来打造珠宝。这一储量比目前已知的全世界钻石矿储量的总和还超出很多。
The Siberian branch of Russian Academy of Sciences said that the Popigai crater in eastern Siberia contains " many trillions of carats " of so-called " impact diamonds " -- good for technological purposes , not for jewelry , and far exceeding the currently known global deposits of conventional diamonds .
