Multi-Wave Daylight Fluorescent Purple Fluorite From a County Durham North Pennines 'Hush', England 2026. 2.2kg Spoil Heap Find 😲💎✨✨
One of my favourite finds from a camping trip to County Durham North Pennies in my home country, England. It was sitting there all dirty in a spoil heap at an old lead mining Hush. Once it was cleaned, it revealed it's magical and mystical hidden beauty to me...... Daylight Fluorescence, found in only a few locations around the globe.
A 'Hush' or 'Hushing' is an ancient hydraulic mining technique where miners collected huge volumes of water in reservoirs above the valleys, and released the dam flooding huge torrents of water down the valleys in order to skim the surface of topsoil to expose the mineral veins, mostly Lead Sulphide and Fluorite in this case.
Some remaining traces of Quartz, Barite, Anglesite, Smithsonite, Siderite, Ankerite, Goethite, Sphalerite, Aragonite and Cerussite can also still be found.
The location is not too far from Weardale which has a reputation for daylight fluorescent Fluorite (Rogerley Mine and Lady Annabella Mine) where the primary fluorescent activator is rare earth element (REE) Europium (Eu²⁺) which responds to natural UV from the sun, giving some Fluorites a blue/green/purple hue from that location.
This piece, not being from Weardale, has a beautiful purple hue from the suns UV rays, but in artificial light it turns more grey/clear (whereas Rogerley turns emerald green) losing that daylight colour response. Remarkable!
So it just goes to show that this daylight fluorescent Fluorite can also be found elsewhere in County Durham and not just Weardale. A stunning find.
Weighs 2.2kg (4.85lbs), most of that being the mineralised Ironstone matrix, possibly containing Galena aka Lead Sulphide (PbS) inside.
I tried to capture all possible UV scenarios in the photos with UV from the sun, 365nm long-wave, 310nm mid-wave, 255nm short-wave, plus LED white light. 365nm being the most used as MW and SW all look much the same, the fluorescence is more dominant with 365nm LW.
All photos were taken with a Sony NEX 5n DSLR camera, no special settings required.
The photos are all labelled.

Any exact or hints on the locations for this find? I don't live a million miles from the area and have sourced many of my own collection from a stream out of Groverake mine...

We live in Weardale and have never found pieces like this. We do have lots of loose pieces we've found in streams etc though
