About this specimen
This beautiful green fluorite from the Diana Maria Mine in England forms a dense group of well-developed cubic crystals intergrown with one another. The crystals show varying degrees of transparency, with areas of deeper green alongside lighter zones that give the specimen considerable depth.
One of the remarkable characteristics of green fluorite from this locality is its daylight fluorescence. Under natural daylight, some areas can develop bluish-green to blue tones, while appearing predominantly green under artificial lighting. This phenomenon is caused by the ultraviolet component of natural daylight, which produces a blue fluorescent emission that combines visually with the green color of the fluorite.
The different photographs allow the specimen to be compared directly under studio lighting and natural daylight. The video provides additional views of the crystal arrangement, crystal faces and variations in color depending on the viewing angle.
Fluorite
Fluorite is a calcium fluoride with the chemical formula CaF₂. It commonly crystallizes in cubic form and can display a wide range of colors and fluorescent responses depending on its locality and composition.
Provenance
The locality is particularly known for its green fluorite and for the bluish daylight fluorescence that some crystals can display.
This fluorite comes from an old collection.
