A well-formed octahedral crystal of black Franklinite measuring to 1.3 cm with many smaller crystals embedded in a white Calcite matrix. This fine small cabinet specimen is from the Franklin Mining District in Sussex County, New Jersey, USA, what is know as the fluorescent mineral capital of the world! Creamy-tan rounded crystals of Willemite are also distributed through and across the specimen. Under LWUV the Calcite fluoresces pale creamy-pink and in SWUV the Willemite bright emerald green. A great Franklin specimen.
