Description: This is a beautiful classic specimen with Willemite and Franklinite from Franlkin Mine (New Jersey, USA). The willemite is green under UV light (365 nm, long wave). Willemite was first recognized in New Jersey in 1822, although it had evidently been mined there for many years before. It was then known as silicious oxide of zinc. The activator that gives the intense-bright green fluorescence in ultraviolet light is Mn(II) which replaces Zn(II).
