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).

ROGERLEY MINE FLUORITE CLUSTER
A beautiful, Rogerley Mine Fluorite Cluster. Featuring well formed crystals and a lovely deep emerald like green which changes to electric blue under UV light or blue green in natural light. 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.

EXCEPTIONAL ROGERLEY MINE FLUORITE
An Exceptional Rogerley Mine Fluorite Specimen. This specimen is museum quality Fluorite and a one-of-a-kind piece. It was found on 30 May 2013 directly behind “The Weardale Giant” the famous large plate found in the Penny’s Zone part of the mine. This beautiful green Fluorite comes from one mine in the world. Fluorite from this mine is world famous for its “daylight fluorescence”, or rare ability to fluoresce in daylight. It is also fluorescent under long and short wave UV light. An essential mineral for the serious collector and a personal favourite!.
The daylight fluorescence is particularly marked in overcast weather, but still noticeable in any conditions. Photos are taken both indoors and outside. We have added a pic of this specimen under long wave ultra violet light, which shows as bright blue. 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).

ROGERLEY MINE FLUORITE
ROGERLEY MINE FLUORITE
A beautiful Rogerley Mine Fluorite Cluster. Featuring gemmy crystals and a lovely deep emerald-like green which changes to bright blue under UV light or sunlight. This is due to its very rare daylight fluorescence. This is very collectible stuff, coming from the only mine in England to operate purely for mineral specimens. Only a limited amount of material will ever come from any of the pockets at the mine. This piece was mined on 14-04-2014. The next year a different pocket was mined. I have taken pictures indoors (the greener ones) and outdoor (blue-green) plus one indoors with a UV light shone over it. My pictures don’t do it justice – we would normally take some pics in our glowroom, which is out of action. The photo with the green leaf background shows natural daylight fluorescence. This spectacular mineral appreciates in value every year.
