Fluorite | Wheal Mary Ann Mine, Menheniot, Cornwall | No. 5

A delicate natural Fluorite specimen from Wheal Mary Ann Mine in Menheniot, Cornwall, displaying beautifully subtle sage-green and smoky grey-green tones.

This 50g specimen features a prominent translucent fluorite crystal with a broad, angular face and naturally irregular edges. Its muted green colouration is particularly attractive, with areas of pale cream and honey-coloured mineral staining around the base.

The crystal displays a combination of translucent and slightly cloudy areas, creating a soft, layered appearance. Under closer inspection, fine internal features and reflective surfaces become visible, adding depth and character to the specimen.

The natural crystal faces exhibit a gentle glassy lustre, while the surrounding fractured surfaces reveal the mineral's distinctive internal structure.

Despite its smaller size, this specimen offers an appealing example of Cornish fluorite, particularly for collectors interested in historic British mining localities and naturally formed mineral crystals.

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.
