Stunning beautiful specimen of YELLOW CALCITE FLUORESCENT. Fluorescent with Long and Short Wave UV. This specimen still has a little dirt on it. Our photos do no justice to this specimens bright colours under fluorescence. This location is now closed. There is a slim layer of bright yellow material in the crust which fluoresces orange, this specimen proved hard to photograph.

WILLEMITE FRANKLINITE CALCITE LARGE
WILLEMITE FRANKLINITE CALCITE LARGE
A stunning specimen of WILLEMITE FRANKLINITE CALCITE LARGE size showing off the brightest fluorescence of all natural minerals Willemite. This rare special specimen is short and long wave fluorescent and phosphorescent. Showing a thin vein of Willemite on pics. Willemite (Green) is associated with Zinc ore and Zinc mining. Shown in pics with short wave UV light. In the light of day it looks like a rock with little chunks of grey metal in it. This specimen is also phosphorescent, like when I take away the SW UV light the Willemite still glows for some seconds. Very cool stuff and this is one of my very favorite rocks. To view this spectacular specimen you will need a UVC Shortwave Lamp. Make sure you wear safety glasses or glasses. The Metallic looking octahedral crystals of Franklinite are shown well in the daylight pics. Some red Zincite can be seen too.

RARE ROGERLEY FLUORITE
RARE ROGERLEY FLUORITE
A beautiful plate of rare Rogerley Fluorite. Deep forest green indoors, changing to a translucent bright blue green outside. This specimen is covered with sharp cubic crystals including several twins. An especially stunning piece, my photos don’t do it any justice. This Fluorite only comes from one mine in the world which is producing less material each year and recently ceased operations. It is daylight fluorescent which is rare and exotic in itself, along with being fluorescent under UV longwave light (the bright blue pic). RocknCrystals are well known for stocking this rare mineral, we have done so since we first started out as mineral dealers many moons ago. We have specimens from several pockets at the mine. Photos taken indoors, outdoors and indoor under longwave ultraviolet light. This Fluorite is an excellent investment and will be a treasured specimen in any collectors cabinet.

14cm x 11.5cm x 4.5cm, 868g.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).
