Red and White Willemite with Franklinite. An extremely Long and Shortwave UV-reactive, phosphorescent old-mine specimen from the ancient mountains of Northern New Jersey, USA. Old active-mine piece from early/mid 20th C. from the then active Franklin Mine. It contained some of the most spectacular geology on Earth, 300 or so different minerals, about 20% of which fluoresce in short or long wave ultraviolet light. This deposit of zinc-iron-manganese ores shaped by the Precambrian are highly metamorphosed and contain minerals in forms that exist almost nowhere else.  These images were taken with a 254 nm Shortwave UV light. 2.5" x 2" x 1", 8 oz.
