D
Most of the world's diamonds come from Africa,but there is one place in the United states where they are found,it is near Murfreeboro,Arkansas.
Diamonds were first found near Murfreeboro in 1906.About fifty thousand diamonds have come from this field.One forty-carat diamond was the largest ever found in North America.But most of the stones were too small to be worth mining.Soon all mining stopped there .Today a visitor to Murfreeboro can hunt for diamonds himself.
A few diamonds have been found in sand and gravel along the Great Lakes,too.But none of these were in their original blue ground.They may have been formed far in the north and carried south by the last great glaciers.

世界上大部分的钻石来自非洲,但在美国一个地方靠近Murfreeboro地区发现了钻石矿--阿肯色.
1960年钻石最早被发现在murfreeboro.大约50000克拉钻石都来自这一区域.40克拉的钻石是有史以来在北美发现规模最大的一颗.但是部份石块太小以致于不值得开采.很快就全部停止采矿.近来游客会到Murfreeboro自己寻找钻石.
许多钻石也是在Great Lakes的沙子和沙砾中找到的.但那些没有被找到的钻石真正的来源其实是Great Lakes.这些钻石可能是在北部形成,然后被巨大的冰川冲带到南部的.
