Alston Moor District, North Pennines, Cumberland, Cumbria, England; 1939
This specimen from a classic English location has black, shiny, sharp Sphalerite crystals scattered across lavender Fluorite. The Fluorite has a small amount of orange iron oxide staining within it. Like most Fluorite from the location, it fluoresces strongly under longwave UV. The color is bright blue/purple. The specimen is in good condition with the exception of some internal fractures in the corner of the largest crystal.
