美國新澤西州薩塞克斯郡福蘭克林自治市〈Franklin is a Borough in Sussex County, New Jersey, United States. As of the United States 2000 Census, the borough population was 5,160.〉，發現超過１５０種以上的礦物，而其中大部分是螢光礦物即超過１００多種，而其中２５種是特殊礦物世界其他地方所沒有，因此我們將 Franklin, New Jersey 稱為螢光礦物之王國。事實上我們先前介紹的螢光礦物已經有不少是 Franklin, New Jersey 所生產，今天我們介紹的是其中的兩件經典標本：
〈一〉下圖是個螢光礦物的集合體，包含的螢光礦物有鋅黃長石Hardystonite，透閃石Diopside，斜晶石Clinohedrite，矽鋅礦Willemite，方解石 Calcite，鋅鐵尖晶石Franklinite 等。其中Franklinite 就是以福蘭克林命名的礦物，以下則是英文説明：

〈二〉這也是個螢光礦物的集合體，包含閃鋅礦 Sphalerite，矽鋅礦 Willemite ， 鋅鐵尖晶石Franklinite ，方解石 Calcite ，水碳鋅礦 Hydrozincite 等。以下是英文說明：
