Fluorite Specimen - Diana Maria Mine, Weardale UK

Fluorite Specimen — Diana Maria Mine, Weardale UK

A superb British Fluorite specimen from the world-renowned Diana Maria Mine in Weardale, County Durham. Prized by collectors globally, Weardale Fluorite is celebrated for its exceptional colour and high UV reactivity. 

Physical Properties

• Fluorite — Chemical Formula: CaF₂ | Hardness: 4 (Mohs) | Crystal System: Isometric (Cubic) | Lustre: Vitreous | Transparency: Transparent to translucent | Colour: Purple, blue-green, yellow, and multi-zoned — characteristic of Weardale locality material

Geology & Formation

The Diana Maria Mine sits within the Northern Pennine Orefield, one of the UK's most important fluorite-bearing geological regions. Fluorite here formed as a hydrothermal mineral, precipitating from hot, mineralising fluids that percolated through fault systems and voids in Carboniferous limestone. The distinctive colour zoning results from variations in trace elements and radiation exposure during crystal growth over hundreds of millions of years. Weardale material is highly sought after and increasingly scarce as mining activity winds down.

Crystal Properties

• Fluorite — known as the “Genius Stone,” associated with mental clarity, focus, and organisation. Believed to absorb and neutralise negative energy, making it popular for study spaces and work environments. Each colour carries additional nuance: purple for intuition, green for the heart, yellow for confidence.
