Zincite
The famous Franklin-Ogdensburg mining district exploited one of the world's most species diverse orebodies, currently with a count of 408 minerals and the type locality to no less than 71, one of which is Zincite. Zincite is a rare zinc oxide (ZnO) and has two co-type localities, although both are at opposite ends of the same syncline orebody, Franklin mine and Sterling mine. This tremendous example is that of crystallized Zincite, a rare occurrence at this mine because it usually forms as anhedral granular infill in void space between grains of, typically, Franklinite and Calcite. Orange-carmine-red crystals to 1 cm across, richly coat a flat plate of what is likely massive Franklinite covered in smears of snow-white Calcite. The base of this specimen is rich in more granular orange red Zincite. In long wave UV light the Calcite fluoresces a dull flesh-pink while various patches of bright green Willemite manifest. A splendid crystallized Franklin Zincite not just in terms of crystal form, but the intense red colour which is rarely seen. Simply stunning.
