Layman's explanation:	An abundance of hardystonite was discovered in Franklin Mine, which is located in Hardyston, Township, New Jersey, by Wolff in 1899. It is well known for its fluorescent properties under short wave UV light. It is normally white to pink in color and is often found, and closely associated, with willemite, rhodonite, and franklinite, and clinohedrite.
