TOP ROGERLEY FLUORITE CLUSTER
Specimen of Top Rogerley Fluorite Cluster from Weardale. We have held the price down on this one so it is very affordable and can be tucked away into your collection for safe keeping. This cluster has good crystal coverage on top, with well formed, clear crystals. We have taken photos indoors, outside and also under long wave ultraviolet light. This particular specimen shows great daylight fluorescence. Grab a piece of geological history now and spend hours admiring the amazing cubic form and fluorescent properties of this great English mineral specimen. We have stocked this incredible green Fluorite since we first started dealing minerals many moons ago. We stock a range of pieces from different pockets at the mine. The mine has now closed down and pieces like this are already rising in value. The large crystal is a little loose but still firm, hence the reduced price.

It’s Fluorite, Jim, but not as you know it! There is a reason people go nuts for Fluorite from this mine in particular – Daylight Fluorescence. Fluorite from the Latin, fluere “to flow” for its use as a flux. Fluorescence from Fluorite. The element fluorine also derives its name from Fluorite, a major source for the element. The daylight fluorescence thought caused by rare earth elements REE, phosphates Monazite, Xenotime and Fluorocarbonates mainly Synchysite. Avoid long exposure to bright light.
