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.

Highly modified cubic crystal. It's a pretty good example from this locality as far as I can tell.

The two large, hexagonal, prismatic crystals at the center are Svabite and has been microprobed (Bart Cannon, 1999) by Forrest Cureton. The longest is 6cm and the shorter crystal is 3cm. There are also a few 2.5cm crystals. The color is consistent with the description. There are also eight pink Rhodonite crystals of which the longest is 2.5cm. Fluorescent photos shown are Calcite (orange glow) and Willemite (green). On the side is a stuck on label. Granular garnet is rich and most associated with the Rhodonite.
Ex. Earl Calvert collection, Rock Currier. Several previous labels accompany the specimen, please see provenance tab.
Incredible specimen, one of which should be in the collection of any serious Franklin collector.
