雨花石是一种天然玛瑙石，也称文石，观赏石，幸运石。雨花石的孕育到形成，经过了原生形成、次生搬运和沉积砾石层这三个复杂而漫长的阶段，也可谓是历尽沧桑方显风流了。 一般提到雨花石人们通常会联想到南京雨花台，都以为雨花石就是产自雨花台一带，实际上这只是人们的误解，事实上主要出产于江苏省南京市六合区以及仪征市月塘一带，为当地开采砂矿的附属物，故而有“一吨黄沙四两石”之说。 所产雨花石之质、形、纹、色、呈象、意境六美兼备，被誉为“天赐国宝，中华一绝”。中国自南北朝以来，文人雅士寄情山水，啸傲烟霞，至唐宋时期达到颠峰。

The Yuhua stone (Chinese:雨花石; pinyin:yuhua shi; literally: "rain flower stone") is a special kind of stone found in Nanjing, China, due to the unique geology of the area. Yuhua stones, or pebbles, are of sedimentary origin and consist of minerals including quartz and other silicates. They are found in the Yangtze River, polished smooth by the action of water.
