Franklinite

Franklinite is a rare mineral typically found in zinc-rich ore deposits, particularly in Franklin, New Jersey, USA. Known for its dark, almost black coloration, it often occurs in combination with other minerals like willemite and zincite. Despite its striking appearance, Franklinite is not commonly used in jewelry due to its hardness and scarcity. Instead, it is highly prized by mineral collectors for its unique crystal formations and historical significance. Its association with the zinc mining industry in Franklin makes it a sought-after specimen among enthusiasts and collectors of rare minerals.
