ROGERLEY MINE FLUORITE CLUSTER BLUE
ROGERLEY MINE FLUORITE CLUSTER BLUE
A beautiful cluster of daylight-fluorescent Rogerley Mine Fluorite Cluster Blue Birds Pocket. This stunning fluorite cluster comes from “Bluebirds Pocket” Zone #2 in the world famous Rogerley Mine in England. It is super- fluorescent, with a bright blue shining through in daylight! My photos don’t do it justice. Featuring several twinned crystals and a lovely deep emerald-like green which changes to electric blue under UV light or sunlight. This is spectacular stuff and very collectible, coming from the only mine in England to operate purely for mineral specimens. There is limited material from this pocket. This specimen is spectacular and would show better Blue colour with an overcast sky, a blue sky has more white light which tends to wash out the blue colour effect from UV light. Three photos taken outdoor show some Blue Daylight Fluorescence, though it is usually more apparent in more overcast weather. The two bluest photos were taken under long wave ultraviolet light in a normally lit room during the day.
ROGERLEY MINE FLUORITE
Fluorite from the Rogerley Mine is highly sought after for its daylight fluorescence and the top quality crystals it forms. This piece is no exception, showing a stunning emerald green colour indoors and turning electric blue when under UV light and some where in between in day light (as the sun naturally radiates UV light). The daylight fluorescence is particularly marked in overcast weather, but very noticeable in any conditions. Photos are taken both indoors, under Long Wave light.
The daylight fluorescence is suspected to be caused by the inclusion of Rare Earth Elements (REE), minerals including phosphates (monazite and xenotime) and fluorocarbonates (mainly synchysite).
