About Hodgkinsonite
Hodgkinsonite is a rare zinc manganese silicate hydroxide mineral occurring as translucent to transparent pink to red prismatic crystals with a vitreous to adamantine luster. It is primarily known from the Franklin zinc deposit in New Jersey, USA—one of the world's most mineralogically rich localities—where it was named after H.H. Hodgkinson, a mining company official. Under ultraviolet light, hodgkinsonite produces a striking orange fluorescence, adding to its appeal as a Franklin mineral collector's specimen.
