Its delicate colouration and historic mining locality make it a lovely addition to a British mineral collection.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Description\u003c\/h3\u003e\n\n\u003cp\u003eThis distinctive specimen displays a beautiful combination of \u003cstrong\u003epale blue-green, soft grey-green, translucent champagne and creamy-white fluorite\u003c\/strong\u003e, with scattered golden-orange and rusty-brown markings.\u003c\/p\u003e\n\n\u003cp\u003eThe specimen has an elongated, naturally irregular formation, with a broad central crystalline section and narrower, angular edges.\u003c\/p\u003e\n\n\u003cp\u003eOne of its most attractive features is the large, softly translucent blue-green crystal face occupying much of the specimen's central surface.\u003c\/p\u003e\n\n\u003cp\u003eThis prominent crystalline area has a delicate sea-glass appearance, with subtle internal cloudiness, fine surface markings and variations in transparency.\u003c\/p\u003e\n\n\u003cp\u003eThe pale blue-green colour becomes slightly deeper in certain areas, while the surrounding edges transition into softer cream, champagne and pale yellow tones.\u003c\/p\u003e\n\n\u003cp\u003eSeveral angular crystal boundaries are visible across the specimen, creating a naturally geometric appearance.\u003c\/p\u003e\n\n\u003cp\u003eThe larger crystalline surfaces display a mixture of glass-like lustre and slightly frosted textures, allowing light to interact differently with each section.\u003c\/p\u003e\n\n\u003cp\u003eFine natural surface markings and irregular crystalline edges add further detail to the specimen.\u003c\/p\u003e\n\n\u003cp\u003eAlong the lower and outer sections, small patches of golden-orange and rusty-brown staining contrast beautifully with the cooler blue-green fluorite.\u003c\/p\u003e\n\n\u003cp\u003eThese markings are consistent in appearance with iron-bearing mineral staining, although their precise composition has not been independently confirmed.\u003c\/p\u003e\n\n\u003cp\u003eOne end of the specimen reveals a more complex arrangement of overlapping, angular crystalline surfaces, with pale champagne fluorite surrounding slightly clearer internal sections.\u003c\/p\u003e\n\n\u003cp\u003eFrom the opposite side, the specimen displays a broad, softly frosted blue-green surface with additional natural mineral staining along its edges.\u003c\/p\u003e\n\n\u003cp\u003eThe contrast between the smoother-looking central crystal faces and the more irregular outer crystalline growth gives the specimen considerable visual interest.\u003c\/p\u003e\n\n\u003cp\u003eIts natural fractures, intersecting crystal boundaries and subtle colour variations are characteristic features of an unpolished mineral specimen.\u003c\/p\u003e\n\n\u003cp\u003eMeasuring \u003cstrong\u003e40.0mm × 66.4mm and weighing 135g\u003c\/strong\u003e, this is an attractive example of pale blue-green fluorite attributed to the historic Wheal Mary Ann locality.\u003c\/p\u003e\n\n\u003ch3\u003eAbout Fluorite\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eFluorite (CaF₂)\u003c\/strong\u003e is a naturally occurring calcium fluoride mineral belonging to the halide mineral group.\u003c\/p\u003e\n\n\u003cp\u003eIt crystallises in the cubic, or isometric, crystal system and has a Mohs hardness of 4.\u003c\/p\u003e\n\n\u003cp\u003eFluorite is particularly admired for its remarkable range of natural colours, including purple, blue, green, yellow, pink, brown and colourless varieties.\u003c\/p\u003e\n\n\u003cp\u003eThese colours may develop through structural defects, trace impurities and geological conditions during crystal formation.\u003c\/p\u003e\n\n\u003cp\u003eBlue-green fluorite can display delicate shades ranging from pale aqua and sea-glass green to deeper blue-grey and greenish-blue tones.\u003c\/p\u003e\n\n\u003cp\u003eVariations in colour and transparency can occur within a single specimen, creating subtle changes in appearance as light passes through different crystalline sections.\u003c\/p\u003e\n\n\u003cp\u003eFluorite commonly forms within hydrothermal mineral veins, where heated, mineral-rich fluids circulate through fractures and cavities in surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eAs these fluids cool or undergo changes in temperature, pressure or chemical composition, dissolved minerals may crystallise within the available spaces.\u003c\/p\u003e\n\n\u003cp\u003eFluorite frequently occurs alongside quartz, calcite, baryte, galena, siderite and other minerals associated with hydrothermal deposits.\u003c\/p\u003e\n\n\u003cp\u003eOne of fluorite's defining physical characteristics is its \u003cstrong\u003eperfect octahedral cleavage\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThis means the mineral can separate along particular crystallographic planes, producing distinctive angular surfaces.\u003c\/p\u003e\n\n\u003cp\u003eAlthough fluorite commonly forms cubic crystals, natural cleavage and breakage can create triangular, stepped and irregular geometric formations.\u003c\/p\u003e\n\n\u003cp\u003eFluorite typically possesses a vitreous, or glass-like, lustre, although natural weathering, fine surface textures and mineral coatings can produce a softer, frosted appearance.\u003c\/p\u003e\n\n\u003cp\u003eSome fluorite specimens exhibit fluorescence under ultraviolet light, although this property varies between individual specimens and localities.\u003c\/p\u003e\n\n\u003cp\u003eUltraviolet fluorescence has not been confirmed for this specimen.\u003c\/p\u003e\n\n\u003ch3\u003eWheal Mary Ann \u0026amp; Cornish Mining Heritage\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWheal Mary Ann\u003c\/strong\u003e is a historic mineral locality situated near Menheniot in south-east Cornwall, England.\u003c\/p\u003e\n\n\u003cp\u003eThe Menheniot district forms part of Cornwall's extensive mining landscape and is particularly associated with historic lead and silver mining.\u003c\/p\u003e\n\n\u003cp\u003eAlthough Cornwall is internationally recognised for its tin and copper deposits, the south-eastern region also contains important lead-bearing mineral veins.\u003c\/p\u003e\n\n\u003cp\u003eDuring the nineteenth century, mining operations around Menheniot extracted lead ores, particularly galena, which could also contain economically valuable silver.\u003c\/p\u003e\n\n\u003cp\u003eThese deposits developed through hydrothermal geological processes, with heated mineral-rich fluids circulating through fractures in the surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eOver time, these fluids deposited a varied assemblage of minerals, including quartz, fluorite, galena, siderite, calcite and other associated species.\u003c\/p\u003e\n\n\u003cp\u003eWheal Mary Ann is particularly interesting because historical geological investigations document complex relationships between successive generations of mineral deposition.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBritish Geological Survey's geological memoir covering Plymouth and South-East Cornwall\u003c\/strong\u003e identifies fluorite as an important gangue mineral at Wheal Mary Ann.\u003c\/p\u003e\n\n\u003cp\u003eGangue minerals occur alongside economically valuable ores but are not necessarily the principal materials being extracted.\u003c\/p\u003e\n\n\u003cp\u003eThe geological memoir describes quartz as a significant vein-filling mineral, with chalcedonic material occurring along portions of the vein walls.\u003c\/p\u003e\n\n\u003cp\u003eCrystalline quartz, galena and siderite are also documented within the mineral sequence.\u003c\/p\u003e\n\n\u003cp\u003eHistorical geological observations indicate that at least two generations of fluorite mineralisation occurred at Wheal Mary Ann.\u003c\/p\u003e\n\n\u003cp\u003eThis suggests that the mineral veins experienced multiple episodes of deposition under changing geological conditions.\u003c\/p\u003e\n\n\u003cp\u003eSuch processes can produce complex mineral associations, overlapping crystalline formations and variations in crystal development.\u003c\/p\u003e\n\n\u003cp\u003eFluorite from historic Cornish localities is particularly appealing to collectors interested in British mineralogy, geological history and the country's mining heritage.\u003c\/p\u003e\n\n\u003cp\u003eThis specimen offers an attractive example of fluorite attributed to Wheal Mary Ann, combining delicate blue-green colouration, broad translucent crystal faces and naturally occurring mineral staining.\u003c\/p\u003e\n\n\u003ch3\u003eIntention \u0026amp; Associated Chakras\u003c\/h3\u003e\n\n\u003cp\u003eWithin traditional crystal healing practices, fluorite is associated with mental clarity, concentration, emotional balance and maintaining a clear perspective.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBlue-green fluorite\u003c\/strong\u003e is commonly connected with calm communication, emotional harmony and clear thinking.\u003c\/p\u003e\n\n\u003cp\u003eIts soft blue-green colouration is traditionally associated with the Throat Chakra and Heart Chakra, symbolically representing communication, emotional balance and peaceful expression.\u003c\/p\u003e\n\n\u003cp\u003eFluorite as a mineral is also frequently associated with organisation, focus and supporting a calm, balanced mindset.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMental Clarity:\u003c\/strong\u003e

broad angular surfaces, overlapping crystal formations and contrasting translucent and opaque areas.\u003c\/p\u003e\n\n\u003cp\u003eIts elongated formation creates an attractive horizontal silhouette, while the prominent central crystal face gives the specimen a distinctive geometric appearance.\u003c\/p\u003e\n\n\u003cp\u003eThe pale blue-green colouration creates a soft, sea-glass quality, contrasting with the warmer champagne and creamy-yellow crystalline edges.\u003c\/p\u003e\n\n\u003cp\u003eSeveral crystal faces display fine natural surface markings, while smaller intergrown sections create additional texture along the specimen's outer edges.\u003c\/p\u003e\n\n\u003cp\u003eScattered golden-orange mineral staining highlights selected crystal boundaries and fractures, adding further contrast to the specimen.\u003c\/p\u003e\n\n\u003cp\u003eWithin traditional crystal symbolism, blue-green fluorite is associated with calm communication, mental clarity and emotional balance.\u003c\/p\u003e\n\n\u003cp\u003eBeyond these symbolic associations, this specimen's principal appeal lies in its delicate natural colouration, distinctive crystalline geometry and connection
