Weardale Fluorite Specimen #2 - Diana Maria Mine, Frosterley, Co Durham, UK

Weardale Green Fluorite Specimen #2

A striking green fluorite cluster from Diana Maria Mine in Weardale, Frosterley, County Durham. This specimen features a layered arrangement of intergrown cubic crystals on a contrasting, earthy brown matrix, with larger cubes rising above a scattering of smaller crystals.

The photographs show the rich green colour within the crystals, paler green faces and areas of translucency that reveal depth beneath the surface. Reflective faces sit alongside naturally textured edges and cloudy patches, giving the piece plenty of detail to enjoy from different angles. A characterful addition to a British mineral collection or a thoughtfully chosen gift for a fluorite enthusiast.

This specimen is UV reactive , adding another feature to explore under ultraviolet light.

Physical Properties

• Mineral: fluorite, calcium fluoride (CaF₂).
• Crystal system: cubic.
• Hardness: 4 on the Mohs scale.
• Appearance: intergrown green cubic crystals with translucent areas and a glassy lustre on reflective faces.
• Matrix: contrasting brown host rock with pale crystalline areas.
• UV reactivity: reactive under ultraviolet light.

Geology & Formation

Fluorite forms when mineral-rich fluids deposit calcium fluoride in veins and cavities within rock. Its cubic crystal structure produces the distinctive block-like shapes visible in this specimen. The named locality is Diana Maria Mine in Frosterley, part of the renowned Weardale mineral district in County Durham.

Crystal Properties

In crystal traditions, green fluorite is associated with balance, clarity and renewal. It is believed by some to support focus and a sense of calm, making it a meaningful piece for a quiet workspace or meditation area. These associations are spiritual beliefs rather than scientifically established effects.
