BLUE AMBER VERY LARGE
BLUE AMBER VERY LARGE
A beautiful Blue Amber Very Large specimen. This is a truly amazing material, indoors it has a translucent golden red hue, outdoors it looks blue to purple, so some kind of fluorescence or natural colour change is taking place here. Under long wave UV light it fluoresces electric blue. Being Amber, or fossilised tree gum, it is extremely light for its size. The ethereal look and feel of this stuff make it a compelling addition to the collection. This piece would be suitable for cutting into a magical looking gem too. Bet you can’t put it down! A great gift or treat for the collector of the unusual.

Jambi Coal Mines, Central Sumatra, Indonesia.Approximately C10H16O; Succinic acid.

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.

WILLEMITE FRANKLINITE CALCITE 789G
WILLEMITE FRANKLINITE CALCITE 789G
A stunning specimen of WILLEMITE FRANKLINITE CALCITE 789G showing off the brightest fluorescence of all natural minerals – Willemite. This rare special specimen is short and long wave fluorescent and phosphorescent. Showing a vein of Willemite on the right of 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 it still glows for 10 seconds after. Very cool stuff and this is one of my very favorite rocks. To view this spectacular specimen you will need a UVC Shortwave Lamp and make sure you wear safety glasses or glasses. The Metallic looking octahedral crystals of Franklinite are shown well in the daylight pics. Some minor red Zincite can be seen too.
