Fluorite | Wheal Mary Ann Mine, Menheniot, Cornwall | No. 4

A beautiful natural Fluorite specimen from the historic Wheal Mary Ann mining locality near Menheniot, Cornwall, featuring translucent smoky-grey, champagne and honey-gold mineralisation with contrasting rusty-orange iron staining.

Weighing 155g, this distinctive Cornish mineral specimen displays substantial crystalline sections, intricate internal fractures and a fascinating combination of translucent and weathered surfaces.

With its warm earthy colouring and documented locality attribution, this specimen makes a wonderful addition to a collection of British minerals, Cornish geology or historic mining specimens.

This attractive Fluorite specimen displays a naturally irregular, chunky formation with prominent translucent crystal sections and warm golden-brown mineral staining.

The main face features smoky-grey and pale champagne-coloured Fluorite, with areas of honey-yellow and amber tones concentrated around the crystal edges and fractures.

Several larger crystalline sections reveal flat, angular surfaces and internal planes that reflect the light, producing subtle silvery highlights and a delicate glassy appearance.

Fine internal fractures and intersecting cleavage surfaces are visible throughout the translucent material, creating an intricate network of natural lines and textures.

Across the upper and outer surfaces, rusty-orange and golden-brown staining provides a striking contrast against the paler Fluorite. These colours are consistent with iron-rich mineral staining commonly encountered in weathered mineral specimens.

Viewed from different angles, the specimen reveals further translucent sections, rough crystalline edges, darker inclusions and naturally fractured surfaces.

The combination of glassy translucency, warm earthy colouring and substantial crystal structure gives this specimen an appealing geological character.

Its natural form has been preserved, allowing the crystal growth, fractures and mineral staining to remain visible.

About the Mineral | Fluorite

Fluorite is a naturally occurring calcium fluoride mineral (CaF2), known for its remarkable range of colours, distinctive crystal formations and occasional fluorescence under ultraviolet light.

It commonly forms in hydrothermal mineral veins when fluorine-rich fluids circulate through fractures in surrounding rock. As conditions change, dissolved minerals crystallise, producing the cubic and sometimes more complex formations associated with Fluorite.

Fluorite has a hardness of 4 on the Mohs scale and possesses perfect octahedral cleavage, meaning it can break along specific crystallographic planes.

The golden-orange colouring visible across this specimen is consistent with natural iron oxide staining, while its translucent sections reveal the internal structures and fractures formed during its geological history.

Wheal Mary Ann Mine | Cornish Mining History & Heritage

This specimen is recorded as originating from Wheal Mary Ann Mine, near Menheniot in southeast Cornwall.

The Menheniot area forms part of Cornwall's historic metalliferous mining landscape, where mineral-rich hydrothermal veins developed in association with the geological processes that shaped the Cornubian granite region.

Mining in this part of Cornwall was particularly important during the nineteenth century, with copper and other metal-bearing deposits contributing to the region's industrial economy.

Fluorite is one of the minerals associated with Cornwall's hydrothermal vein systems. Although not generally the principal commercial target of the region's metal mines, it can occur alongside quartz, sulphide minerals and other vein-forming minerals.

The combination of translucent Fluorite, natural staining and visible crystal structure makes this specimen an appealing example of the mineral diversity associated with Cornwall's historic mining districts.

Provenance note: Wheal Mary Ann Mine, Menheniot, is the supplied locality for this specimen. Its individual extraction date and precise position within the mine workings are not documented.

Fluorite | Spiritual Properties & Associated Chakras

In crystal healing traditions, Fluorite is associated with mental clarity, concentration, energetic balance and the ability to approach situations with a calmer, more organised perspective.

It is often chosen by those seeking to clear mental distractions, strengthen focus and encourage thoughtful decision-making.

Associated Chakras: Third Eye Chakra and Crown Chakra.

Associated Intentions: Mental clarity, focus, balance and spiritual growth.

These associations are based on traditional crystal healing beliefs rather than scientifically established effects.
