This is a really fine big Franklin Ore specimen with huge black octahedral Franklinite crystals to 3cm on course crystalline Franklinite and Willemite matrix. Of course all the Willemite fluoresces bright green under UV light, see pop-up photo. Also, a label from the University of Chicago - Dept of Geological Sciences accompanies this specimen with the number 1093 that corresponds to a number on the side of the specimen. The specimen most likely originated from Paul Moore.
According to the Bateman's classic work "Economic Mineral Deposits" - Second Edition (1950), which although it is over 60 years old still has great relevant information on deposits, the Franklin-Sterling Hill Zinc District has been mined since 1840 and is unique with no known counterpart in the world.
