This specimen is notable for several reasons. On the one hand a very nice franklinite octahedron, an unusual iron and zinc oxide, with good size, and curved and brilliant faces (17 x 17 mm). On the back side it has some fractures that allow us see the metallic luster. On a matrix of calcite. On the other hand, we have a doubly terminated prismatic crystal of willemite, also with good size (17 x 10 mm). Willemite species usually presents fluorescence, and in this case, under shortwave UV light (also in the longwave UV), it has an intense yellowish green color. Calcite from Franklin is also notable for the intense red-orange fluorescence. In one specimen we have two species with good crystals and size.
